Update to TaskChampion-2.0.2

[djmitche]

This includes a fix for GothenburgBitFactory/taskchampion#527. For taskchampion-py it's a simple version bump.

Seems like the clippy report step cannot be completed on the forked repos.

https://github.com/actions-rs/clippy-check/blob/b5b5f21f4797c02da247df37026fcd0a5024aa4d/README.md?plain=1#L70

Limitations
Due to token permissions, this Action WILL NOT be able to post clippy annotations for Pull Requests from the forked repositories.

I think that's because the PR is from another repository (my fork).

Sorry, I didn't read the whole comment before replying from my phone this morning.

I think this is OK -- the check will still fail if any denied lints are detected, but it won't put comments in the PR diff. If that happens it's straightforward to run cargo clippy (or even cargo clippy --fix) locally to see the same output.
