Consider moving sunpy custom CTYPE mapping from astropy source and update mapping from sunpy

[samaloney]

Provide a general description of the issue or problem.

Essentially move these plus the two at the end to a new dictionary in sunpy SUNPY_CTYPE_TO_UCD1

https://github.com/astropy/astropy/blob/cf99b9e7761c45c15ddc060a76b563574f525df9/astropy/wcs/wcsapi/fitswcs.py#L117-L126

and then somewhere in sunpy

astropy.wcs.wcsapi.fitswcs.CTYPE_TO_UCD1.update(SUNPY_CTYPE_TO_UCD1)

At the moment it hard to know about these as they aren't in the sunpy source code and need to reply on astropy if ever had to change or add new ones. Also if astropy/astropy/issues/16339 is solved would have control over both side in the sunpy source.
