I think this happens because you are using Python 3.7 to build your documentation but astropy==5.0.2 requires at least Python 3.8. See https://github.com/astropy/astropy/blob/v5.0.2/setup.cfg#L35

You should use build.tools.python in your config file to define the Python version, https://docs.readthedocs.io/en/stable/config-file/v2.html#build-tools-python
