Bump dependencies

[centromere]

Note: Section 3.5.3.1 of the OCFL specification requires that UTC be represented by "Z", not by "+00:00". The unit tests have been updated accordingly.

@centromere Thanks for the PR. I'll take a look at it when I have a chance, though I don't think I agree with you about the timestamp format.

After re-reading the OCFL spec and RFC3339, I believe that the spirit of the law is to allow both representations.

I have not investigated too deeply, but I believe a dependency, after being bumped, is now emitting Z instead of +00:00. I do not yet know which dependency or what would need to be changed to get it to emit +00:00. Given that they are semantically equivalent, it was easier for me to modify the unit tests than to track down why the behavior of the dependency changed.

@centromere Interestingly, there was a timezone related failure in CI, but it didn't fail for me locally. In the mean time, I tried updating the crusty old github actions and applied all of the clippy fixes. Do you want to rebase your PR, and try again?

@centromere Try changing the timestamp in the assert in commit_should_pretty_print_inventory to

timestamp.to_rfc3339_opts(SecondsFormat::Secs, true)

Thank you.
