Deactivate broken CI workflows

These workflows try to install the gpg dependency of alot via pip but
since c1137ea it is required as > 1.10.0 and such a version is not
currently available on PyPI.

See #1630 for context.  When the dependency problem is resolved these
workflows can be activated again.
