Not all tags can be checked out with ibc-proto-compiler clone-sdk

Summary of Bug

The --tag option introduced in informalsystems/hermes#369 allows checking out a specific tag with the following invocation

$ ibc-proto-compiler clone-sdk --tag v0.39.1-rc3 --path /tmp/sdk

Unfortunately, this works fine for many tags (eg. v0.39.1-rc3) but not for some others (eg. v0.40.0-rc2).
The latter will fail with Could not find tag v0.40.0-rc2 as git2 does not list v0.40.0-rc2 as part of the tags present in the checked out repository.

It might be that such tags cannot be found because they lack a corresponding tag object, which is usually created by passing either of -a or -s to the git tag command.

$ cargo run -- clone-sdk --tag v0.40.0-rc2 --path /tmp/sdk

We do not use this command anymore, and instead are checking the repositories directly via git in the scripts/sync-protobuf.sh script.
