ci: format code and add ci check for robotframework formatting

[reubenmiller]

Proposed changes

Run just format to apply the formatting to the code base due to:

• Latest Rustfmt nightly results in new formatting
• Some Robotframework tests weren't formattinged before

To avoid committing unformatted Robotframework tests, the format-check was extended to also check the formatting of the Robotframework tests as well which is run on PR checks.

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Improvement (general improvements like code refactoring that doesn't explicitly fix a bug or add any new functionality)
• Documentation Update (if none of the other choices apply)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist

• I have read the CONTRIBUTING doc
• I have signed the CLA (in all commits with git commit -s)
• I ran cargo fmt as mentioned in CODING_GUIDELINES
• I used cargo clippy as mentioned in CODING_GUIDELINES
• I have added tests that prove my fix is effective or that my feature works
• I have added necessary documentation (if appropriate)

Hmm... cargo-fmt pushing too far.

[reubenmiller]

Yep. And I always forget to do a rustup update to update all of the Rust components, so it took me awhile to actually run the required version of Rustfmt
