As a fix for T270588: OAuth 2.0 error on PHP 7.4, I'm bumping league/oauth2-server (8.1.0 => 8.2.4) in MW-1.35-release
This brings in PHP 8.0 support, also fixing PHP 7.4 log noise...
But this will mean our fork (which AFAIK is based on 8.1.0?) will be behind REL1_35, which is a bit meh
I don't think this is a blocker for T245757: Upgrade MediaWiki clusters to Debian Buster (debian 10), as we're "only" going to PHP 7.3 (eventually, AIUI), but it'd be nice to keep these thing in sync, and not get caught out by it again later
