refactor: one emudeck script-to-profile rule

The target scraper kept its own copy of the EmuScripts table and took
.ps1 files the platform scraper never read, so emudeck-we's template
skeleton was published as a core and removed afterwards by an override.
Both scrapers now read emulator_of_script, and the platform scraper
lists the installers at the pinned revision, as launchers: and the
SteamOS target already did. Targets rescraped, override dropped.
