fix: restore --ozone-platform=x11 default in package.json (IsmaelMartinez#2511)

PR IsmaelMartinez#2509 ("docs(roadmap): capture 2026-05-07 ozone-platform default reset
session") accidentally bundled a package.json change that flipped the flag
from =x11 to =auto. =auto is not a valid value for --ozone-platform —
Chromium aborts with `FATAL:ui/ozone/platform_selection.cc:46 Invalid ozone
platform: auto`, making every build cut from main since 2026-05-07
unlaunchable on every distro and packaging format.

Restore the working =x11 default. The proper "remove the flag entirely and
let Chromium auto-detect per session" direction is being handled separately
on IsmaelMartinez#2506; this is the minimum patch to keep main releasable until that lands.
