icrs frame incorrectly uses 1.0.0 tag

[braingram]

import asdf
import astropy.coordinates
af = asdf.AsdfFile()
print(af.extension_manager.get_converter_for_type(astropy.coordinates.builtin_frames.icrs.ICRS).extension)

prints

<ExtensionProxy URI: asdf://asdf-format.org/astronomy/coordinates/extensions/coordinates-1.0.0 class: asdf.extension._manifest.ManifestExtension package: asdf-astropy==0.12.0.dev45+g706c0482c legacy: False>

For some reason the FrameConverter hard-codes 1.1.0:

asdf-astropy/asdf_astropy/extensions.py

Line 496 in 0b8f857

"tag:astropy.org:astropy/coordinates/frames/icrs-1.1.0",

(instead of a wildcard) and also 1.1.0 is no picked up.
