Build tooling updates and fixes. (#974)

* Build tooling updates and fixes.

I stared with documenting how to regenerate protos, and found a few
things that were blocking release, and also was just broken.

So this PR includes:

* Documenting how to regenerate protos with `cargo` and `make`.
* `make` targets for generating protobuf
* Fixes and updates for build tooling for release.
* Updates to rust version - which aligns with the available darwin
  builder image tags.
* Replace `live-server` which broke as unmaintained with `browser-sync`
  which is also way better.

* * Fixes for lint issues.

* Rollback to rust 1.77.1

* There's a joseluisq/rust-linux-darwin-builder:1.77.1 image, but no
  1.77.0 image 🤷🏻‍♂️ - so need to update so we can release macos
  binaries.
* Can't upgrade to 1.78.0 because of
  tikv/pprof-rs#232

+##### Generating Protobuf Files

+If you are adding or editing the `.proto` files in this repository, they will need to be regenerated. To do this,
+you will need [protoc](https://grpc.io/docs/protoc-installation/) installed locally.
+
+Then run:
+
+`cargo run -p proto-gen -- generate`
+
+Which will identify changes in protobuf definitions and regenerate code appropriately.

-
-* If you are running on an arm64 machine, such as an M1 Mac, `make build-macos-binary` to build an amd64 macOS 
-  binary will fail. Depending on your setup, it may be possible to use `BUILD_LOCAL=1 make build-macos-binary` to 
-  attempt to build the binary with local `cargo` tooling. This is generally only a release time task, so we expect

 `make test` will run all tests for this project, except the [Agones](https:/agones.dev) integration tests.
