time to bump to v20 already? This is the current LTS version

[terragady]

bump for pnpm is pretty important as the current version is not able to find newest releases of npm packages

Thank you for the pull request but this is a duplicate of #8925 and #8275

@yeikel pnpm v8 and v9 use different lockfile formats, so this is not a duplicate.

pnpm v9 still does not work at all. ✨
