Backfill PCEE2 as a PS2 alternative emulator in ES-DE

Browse Source 
The PCEE2 libretro core (a separate, actively-developed PCSX2 port,
WizzardSK/pcee2-libretro) is only in ES-DE's own bundled es_systems.xml
as of 3.5.0, which hasn't been released yet - confirmed against ES-DE's
own CHANGELOG.md and by diffing the v3.4.1 tag's real ps2 system block
against git master's (identical except for this one missing <command>
line). ghcr.io/games-on-whales/es-de:edge always installs the latest
*released* AppImage (confirmed against gow's own Dockerfile, which
queries GitLab's releases API), so the container this repo runs
genuinely has no PCEE2 entry at all yet - not a missing core download,
a missing menu entry.

Backfills it via the same esde-custom-systems/es_systems.xml mechanism
already used for the TI-99/4A and Wii U customizations, replicating the
real v3.4.1 ps2 block verbatim plus the one new command (as the default,
matching upstream's own placement). The core file itself needs no extra
handling - confirmed live against the libretro buildbot that
pcee2_libretro.so.zip is already covered by the normal RetroArch cores
pre-download.

# ── PS2: backfill the PCEE2 RetroArch core as an alternative emulator ──────
# ghcr.io/games-on-whales/es-de:edge only ever installs ES-DE's latest
# RELEASED AppImage (confirmed against gow's own apps/es-de/build/Dockerfile
# — it queries GitLab's releases API for the newest tag, not git master),
# which is currently v3.4.1. PCEE2 (a separate, actively-developed libretro
# PCSX2 port, WizzardSK/pcee2-libretro) was only added to ES-DE's own
# bundled es_systems.xml under "Version 3.5.0 (in development)" — confirmed
# against ES-DE's real CHANGELOG.md and by diffing the v3.4.1 tag's actual
# ps2 system block against git master's: identical except for this one
# missing <command> line. So on the version this container actually runs,
# "PCEE2" genuinely isn't in the alternative-emulators list at all yet —
# not a missing download, a missing menu entry. This backfills it (as the
# new default, matching upstream's own placement) while every other field
# and command is copied verbatim from the real v3.4.1 block, so nothing
# else about the ps2 system changes. The actual pcee2_libretro.so core
# file doesn't need any extra download step here — confirmed live against
# the libretro buildbot's own index that it's already covered by this
# installer's normal "./manage.sh cores all" (the default RetroArch core
# pre-download prompt below), same as every other libretro core.

RetroArch and the standalone RetroArch app (if you added it) share the
same \`retroarch/\` cores/saves/system directories.
**PS2 has three RetroArch-core alternative-emulator labels — PCEE2,
LRPS2, and PCSX2** — and it's worth knowing they're not three different
cores: LRPS2 and PCSX2 both point at the exact same file
(\`pcsx2_libretro.so\`, ES-DE's own naming carried over from when the core
was called LRPS2 upstream), while **PCEE2** (\`pcee2_libretro.so\`) is a
genuinely separate, actively-developed libretro port
([WizzardSK/pcee2-libretro](https://github.com/WizzardSK/pcee2-libretro)).
ES-DE only added PCEE2 as an alternative emulator (as the new *default*,
in fact) in version 3.5.0 — confirmed against ES-DE's own CHANGELOG.md —
which hasn't been released yet as of this writing, so the actual ES-DE
build \`ghcr.io/games-on-whales/es-de:edge\` ships (it always installs the
latest *released* AppImage, confirmed against gow's own Dockerfile) is
still on 3.4.1 and genuinely has no PCEE2 entry at all. This installer
backfills it via \`esde-custom-systems/es_systems.xml\` (same mechanism as
the TI-99/4A and Wii U customizations above) so it shows up as an
alternative — and as the default — regardless. The core file itself needs
no special handling: it's on the official libretro buildbot like every
other core, so the normal RetroArch cores pre-download below already
covers it.
The Dolphin core's \`Sys\` folder (compatibility DB + IPL data it needs to
boot Wii titles at all) is fetched automatically now, right after the core
itself downloads — no more manual trip through RetroArch's own Online
