Chore: add python 313

[JanEricNitschkeAA]

Description

Enabling python 3.13 in the pyproject.toml

Before Merging

• Review the code changes
  • Unused print / comments / TODOs
  • Missing docstrings for functions that should have them
  • Consistent variable names
  • ...
• Update changelog.md if necessary
• Commit messages should contain a semantic label and the ticket number
  • Consider squashing if this is not the case

There is still the issue that the aleph-alpha-client requires <3.13 in the latest version. So we first need to resolve this.

  - aleph-alpha-client requires Python <3.13,>=3.9, so it will not be satisfied for Python >=3.13,<3.14
