Versions >= 21 have tags, and will be available via uscan, but depend
on libdalang, which is not packaged for Debian yet.

Versions < 21 were not tagged in the git repository.  Each version has
its own branch, and once a version branch has been publicly released,
it does usually not receive commits anymore.

Debian revision 20.2-1 is based on commit
a94134ebc787bd4523f6790470dd0965e7f9a5e7, head of branch 20.2 when
this was written.

In order to reproduce it:
# version=20.2
# hash=a94134ebc787bd4523f6790470dd0965e7f9a5e7
# (cd .. && wget https://github.com/AdaCore/aws/archive/$hash.tar.gz)
# mk-origtargz --repack --compression=xz --version=$version ../$hash.tar.gz
