Disable galaxy-importer docs tests (#1270) (#1281)

[PR #1270/4435c8a6 backport][stable-2] Disable galaxy-importer docs tests

This is a backport of PR #1270 as merged into main (4435c8a).
SUMMARY
Because galaxy-importer tests the collections in a sterile environment it can't read the shared amazon.aws fragments.
We're separately testing the docs more thoroughly using a github action, so we can disable the broken docs fragment testing via galaxy-importer
