Update for ASDF standard 1.6.0

[braingram]

This PR updates this asdf extension for new versions of:

• asdf-standard
• asdf-coordinates-schemas
• asdf-transform-schemas

CompoundManifestExtension was removed (as it is no longer required)

and updates the CI to account for:

• astropy dev requiring python 3.10
• remove testing against a bunch of random old numpy versions
• separate astropy-dev and numpy-dev testing
• missing python 3.12 testing

a pytest upper pin was added to deal with: scientific-python/pytest-doctestplus#243
when merged an issue can be opened to track removal of this pin EDIT: a new version of pytest-doctestplus was released that fixed the issue
