chore: cargo update

- Had to remove the test checking for manpages to be generated for
  the keygen command since clap-mangen disabled creating manpages
  for hidden commands.

- Had to pin home to the previous version because it now requires a
  new rust version without major version update
- Changed util/src/fd tests due to false positives in CI
  > note: panic did not contain expected string
  >      panic message: `"fd != -1"`,
  > expected substring: `"fd != u32::MAX as RawFd"`
