Build passes but documentation is not updated

[thorstenwagner]

Details

I've updated my documentation and the build passes. On github, everything looks fine but the readthedocs documentation is not updated

Basically the same issue that was reported here:
#6540

That's the documentation on github:
https://github.com/MPI-Dortmund/tomotwin-cryoet/blob/dev/docs/tutorials/tut01_reference.rst

That's the read the docs page:
https://tomotwin-cryoet.readthedocs.io/en/latest/tutorials/tutorials_overview.html#tutorial-1-reference-based-particle-picking

Expected Result

An updated documentation

Actual Result

Github is up-to-date but the readthedocs documentation was not updated

What went wrong?

Hm, now it is updated. It seems to be that there sometime quite a long delay.
