[PRQ#54102] Merge Request for widevine

MarsSeed [1] filed a request to merge widevine [2] into chromium- widevine [3]: Eliminating dupication. 'widewine' was submitted to AUR in 2015, 'chromium-widewine' in 2023. 'chromium' in the pkgname is an essential differentiator, as both packages are only for Chromium-based browsers, i.e. this widevine plugin is not compatible with e.g. Firefox.
