Merge upstream changes

[polyamAdmin]

:warning: Bumps ruby version to 3.3.3

Conflicts:

• .rubocop_todo.yml Upstream removed some rules. Polyam-glitch had an extra ignore. Removed rules upstream did.
• README.md Upstream changed ReadMe. Polyam-glitch has its own. Kept current.
• app/helpers/admin/action_logs_helper.rb Upstream implemented a fix that was already in polyam-glitch. Matched code with upstream.
• app/javascript/mastodon/locales/en-GB.json Upstream deleted string modified to say "toot". Deleted string as upstream did.
• app/javascript/mastodon/locales/en.json Same as above. Additionally replaced "post" with "toot" in new strings.
• app/views/admin/custom_emojis/index.html.haml Upstream changed a line close to additional polyam-glitch code. Ported upstream change.
• app/views/admin/reports/_actions.html.haml Upstream made code style changes close to additional polyam-glitch elements. Ported change.
