[rules_swift] override tarball deps to either use .zip or source checkouts

[jerrymarino]

There's an ongoing issue with tarballs on github: https://github.com/orgs/community/discussions/45830 and rules_swift points at many of the non-release URLs:

ERROR: An error occurred during the fetch of repository 'com_github_apple_swift_log':
ERROR: An error occurred during the fetch of repository 'com_github_apple_swift_nio_http2':
ERROR: An error occurred during the fetch of repository 'com_github_apple_swift_nio':
ERROR: An error occurred during the fetch of repository 'com_github_grpc_grpc_swift':
ERROR: An error occurred during the fetch of repository 'com_github_apple_swift_protobuf':
ERROR: An error occurred during the fetch of repository 'six':
ERROR: An error occurred during the fetch of repository 'com_github_apple_swift_nio_extras':
ERROR: An error occurred during the fetch of repository 'com_github_apple_swift_nio_transport_services':

We can use the zip URLs as a stopgap until there is a conclusion about what the resolution is - or just leave them as a zip. It isn't clear if they'll provide taballs back.

In rules/repositories.bzl - we should declare the depenecies upstream of rules_swift for now

This was the offical comms from github that indicates they won't revert it:

plot twist, revert on the way: bazel-contrib/SIG-rules-authors#11 (comment)

Yep, the nice thing is that moving to either zips or source is that it'd work in the case of this - though with github actively mitigating this I think it's probably file to close out for now and come up with a better plan longer term
