Merge #1247: ci: pin home dependency to 0.5.5 and check_clippy to rust stable version

e7fbc8b ci: run clippy_check with rust stable (Steve Myers)
2251b8d ci: pin home version to 0.5.5 for 1.63 MSRV (Steve Myers)

Pull request description:

  ### Description

  Fixed 1.63 MSRV error by pinning `home` dependency to `0.5.5`, and `clippy` error by changing `check_clippy` job to using rust `stable` version.

  ### Notes to the reviewers

  It's OK to use rust `stable` version for clippy because we already have a `clippy.toml` file to tell it which version of the clippy rules to check against.

  ### Changelog notice

  None
