Make more strings localizable

[skueee]

This commit moves several hard-coded strings to localization files to make them translatable.
The biggest change is the mods descriptions, but there are also some changes in the editor, the matchmaking system, the score ranking statistics screen, and the spectate screen.

1. strings used in rulesets currently do not support localisation, as described in Ruleset projects should be able to contain localisation strings #35641
2. based on the first point, mods' descriptions and parameters also shouldn't be localised, because it would lead to some confusion
3. ranked play is currently WIP and the interface will be completely redesigned in the future, so localising it is useless
4. size. who should be the person who checks a 1k lines of code in one commit?
   changes should be separated according to their's scope

congratulations, you just wasted a ton of time

please try and avoid belittling new contributes

you've made some changes that change everything except localisation

what does this one mean?

P.S.: You created osu fork just yesterday, so i don't rule out that some of the code was written using AI tools, which violates CONTRIBUTING.md

i'd rather we don't start by threatening new users. at that point i'll just turn off PRs to avoid this contention.

sorry for the unintentional rage, should be better now
