Describe the bug
cubi-tk isa-tab validate is simply a wrapper about altamisa isatab validate. However altamisa was changed ~1 year ago to use typer and the isatab_validate.py run function was replaced by main. cubi-tk as not been changed accordingly and the pinned altamisa commit (817dc4) already includes this change.

To Reproduce
Steps to reproduce the behavior:

1. Use cubi-tk version 0.5.*
2. Attempt cubi-tk isa-tab validate dummy-file

Expected behavior
cubi-tk should either pin altamisa release 0.2.9 or adapt the code to run the proper altimasa isatab validate entry point function.
