Abdessamad Derraz 4d3f589ef4 refactor: drop the archived platform status
RetroPie was the only platform with status: archived, which kept it out
of verify --all, slots, the pipeline and list_platforms unless
--include-archived was typed. release_pack already decides which packs a
release publishes and the installer serves every platform, so the status
set nothing apart. The field, its schema entry and the flag are gone, and
RetroPie is covered by every full run like any other platform.

"""A platform that inherits another one.
The child was merged over the parent's cached config: its overrides rewrote
the parent's systems for the rest of the run, and the parent's registry
fields hid the child's own, so RetroPie loaded as active with RetroArch's
scraper and install block.
