[core] Fix CI on v5.x branch

[oliviertassinari]

The v5.x branch is full or failing CI builds, proof: https://github.com/mui/material-ui/commits/v5.x/. This can't work, so here is a quick fix.

1. I ran npx update-browserslist-db@latest and commit the changes.
2. I had

Error [BrowserslistError]: [BABEL] /Users/oliviertassinari/material-ui/packages/mui-styled-engine/src/GlobalStyles/GlobalStyles.js: Unknown version 74 of op_mob (While processing: "/Users/oliviertassinari/material-ui/node_modules/.pnpm/@babel+preset-env@7.23.9_@babel+core@7.25.2/node_modules/@babel/preset-env/lib/index.js")\n' +

I looks like that version never existed https://caniuse.com/ciu/comparison

if I understand browserslist/browserslist#537 correctly.

3. Some of the tests were outdated
4. Some of the formatting script run an different output

I guess technically you'd want to choose a lower version rather than a higher one, but if it always reverted to the desktop version before and we're not altering that one there shouldn't be a problem. (I guess?)

@Janpot The problem is that Opera Mobile 12 was released so long ago, e.g. v18 was in 2013: https://blogs.opera.com/desktop/2013/11/opera-18-landed/. Opera Mobile 80 uses Chromium 120 which is 2023 ish.

Now, yeah, I don't want us to be depending on the next time we get this error: https://app.circleci.com/pipelines/github/mui/material-ui/137830/workflows/405559b1-5afa-4b28-8711-c615bf96bd30/jobs/743026

Instead, I'm going with browserslist/browserslist#543 (comment). No thanks, we want to keep our build idempotent.
