CI-fixes PR #1: pyright is ready to replace pyre

[bernhardkaindl]

Now, pyright is ready to replace pyre (obsolete):

The short summary is:

• It mostly removes obsolete pyre suppressions and replaces pyre with pyright
• The only changes in xcp/ are removed pyre-suppressions and a safe typing comment for pyright.

Full summary:

• As the preparations are complete, activate use pyright (Python analsyis server of VS Code)
• Retire pyre (Facebook's Python static analysis tool):
  • It's not as good as inferring types as Pyright, needs a lot of hand-holding and suppressions.
  • It is many times slower than Pyight
  • It is not integrated into any IDEs (or at least not as well as Pyright, used in VS Code)

As pyre is inferior in every aspect, replace it with Pyright (already used in pre-commit):

• tox.ini: Complete the transition from pyre to pyright
• pre-commit: Remove the remaining call to pyre in pre-commit
• docs: Complete the transition from pyre to pyright
• tox.ini/pyright: Fail tox if pyright fails (enforce check)
• Cleanup the obsolete pyre-error suppressions
• Fix remaining pyright errors and warnings
