Added MSRV check

[Razican]

This Pull Request is a follow-up of #3290.

It adds a test for the MSRV to the CI, so that we don't get similar issues in the future.

Can we read the root Cargo.toml from CI? it would be ideal to check using the provided rust-version from our config.

Second the idea regarding reading the version in the Cargo.toml if possible.

[Razican]

Will see how to do this this weekend :)

@jedel1043, @nekevss this should be ready now :)

[nekevss]

Was double checking the run and noticed a deprecation warning. Maybe adjust it to use $GITHUB_OUTPUT?

[jedel1043]

Nice improvement!

[HalidOdat]

Looks perfect to me! :)
