tonic: 🍸 patch tonic dependencies

fixes #4392.

in #4392, we found an issue with gRPC reflection when recent versions of
`grpcurl` were used to list supported endpoints.

this was tracked down and fixed in #hyperium/tonic#1701, in
collaboration with @conorsch. that pr targets the more recent 0.11 tonic
release however, which we are not yet using.

eventually we should upgrade to tonic 0.11 (see #4400). as a short-term
measure, but we want to unblock engineers from Skip working on an
integration with Penumbra. this commit patches the `tonic` dependencies
used to point to a temporary fork of the `tonic` repo, where i have
backported that patch (and some ci-related fixes) to the 0.10 release.
