chore: deps update (#11981)

# Which Problems Are Solved

After merging #11968 and rechecking the dependabot alerts there are
still some issues leftover.

# How the Problems Are Solved

This pr makes overrides for vulnerable transitive depdencies to force
update to safe versions.
It also upgrades the next.js version in the docs and I also ran `pnpm
update` once more.

# Additional Changes

Removed the mochaawesome dependency is this is not really needed and
seems unmaintained.

# Additional Context

- Precursor: #11968
