Dependabot needs to update src/tc/rust/Cargo.*, too

[djmitche]

This file is part of the cmake build process, and is getting left behind in the updates. This means when CMake builds it, src/tc/rust/Cargo.lock gets updated and causes spurious diffs.

I don't know how to fix this, so un-assigning.

(TBH, my thoughts have tended recently toward breaking TC back into its own repo..)

[djmitche]

Taskchampion has now been broken out, so we have the following Cargo.* files:

Cargo.lock
Cargo.toml
src/tc/lib/Cargo.toml
xtask/Cargo.toml

I think this is less a CMake issue at this point, so probably easier to fix.

https://github.com/GothenburgBitFactory/taskwarrior/pull/3470/files just successfully updated Cargo.lock, which is what we want in this repo. The Taskchampion repo may also require modifications to the Cargo.toml specs for its dependencies.
