feat!: Rename tket2* libs to tket* (#987)

This affects both rust and python libraries.
Since we are renaming the main packages, I just renamed all the
sub-crates / libs too to keep thing consistent and reduce confusion.

Extension names have **not** been updated, as I worry about further
breakage.
Should we update them (in a separate PR)?

### Project breakage

- For dependents, the breakage should be limited to having to update the
dependency names and some types like `Tk2Op` to `TketOp`,
`TKET2_EXTENSION` to `TKET_EXTENSION`, etc.

- For the local automation, I tried to update the workflows as much as
possible, but we can only test them once merged.
- `release-please`'s manifest has been updated. I'll recreate the last
python release tags without the `2`, and the workflow should pick up
from there. We'll need to swap some pypi API keys before merging the
release PR.
- `release-plz` will probably get confused with which commits should be
picked.
- ~It also does not have permission to publish new crates, so we'll need
to manually push `tket-hseries` and update the API keys.~
- Both the `tket` and `tket-qsystem` crates have been created and setup
for trusted publishing, so the release should work correctly.
  
### Follow up and deprecation.

We'll need to make patch releases for the `tket2*` libraries adding a
deprecation warning to the README and directing users to the new
libraries.

- Por python, take a look at the `pypi-rename` [README
template](https://github.com/simonw/pypi-rename/blob/main/%7B%7Bcookiecutter.old_package_name%7D%7D/README.md).
- For rust, make sure to update both the README and `lib.rs` rusdocs.
- Rustdoc recently added support for warning boxes:
[rust-lang/rust#106561](https://www.github.com/rust-lang/rust/pull/106561)

BREAKING CHANGES: Yes
