Add support to python 3.13 (#466)

Also disable 'attest-build-provenance-github': seems to be broken at the moment:

  ```
  Run actions/attest-build-provenance@v1
  Run actions/attest-build-provenance@f1185f1
  Error: Failed to get ID token: Error message: Unable to get ACTIONS_ID_TOKEN_REQUEST_URL env variable
  ```
