Release v1 reflection changes as 1.4.2

[conorsch]

The most recent published release, 1.4.1, does not support the grpc.reflection.v1alpha.ServerReflection -> grpc.reflection.v1.ServerReflection changes from #314. Our project recently updated to v1, and in the process, lost introspection via grpcui.

Could we get a tagged release for 1.4.2, flushing the current contents of main, as well as a new container build?

The workaround in the meantime is to build from source. At time of writing, commit 483f037 worked great for supporting v1 reflection.

Many thanks for the great project!
