I would like to explore the new eslint v9 and migrate to FlatConfig, so if nobody else has something against that, I would like to "claim" this PR and address some of my time in the upcoming days for this

These are getting not applied somehow right now 🤔

• We should wait until ESLint v9 compatibility gund/eslint-plugin-deprecation#78 is solved

[ST-DDT]

I can confirm that pnpm eslint . freezes if pnpm run build was run/when dist exists. Same for docs/.vitepress/cache not sure how that gets created.

[Shinigami92]

Meanwhile in another project I tested out eslint v9 using ESLINT_USE_FLAT_CONFIG=false and it destroys VSCode's eslint extension, so no auto-fix suggestions are made in VSCode anymore at all.
So using this strategy to at least bump up the dependency is non-viable 😕
