Permissions error running make locally

[haydentherapper]

There is a permissions error when trying to read the lock generated during rust codegen. This appears to surface after the rust codegen is complete and a later step accesses the lock (which appears to occur during json schema generation)

Building docker image for generating JSON schema files
docker build -t jsonschema-specs-build -f Dockerfile.jsonschema .
error checking context: no permission to read from '/usr/local/google/home/hayden/protobuf-specs/gen/pb-rust/target/debug/incremental/sigstore_protobuf_specs_codegen-233wpt7eagx8m/s-gu0xx5y87x-120l4cw.lock'
make: *** [Makefile:89: docker-image-jsonschema] Error 1

Running with sudo fixes this, but obviously is not ideal (and seems to create other errors for me, but that's probably due to my environment).

Oh this might be more than just Rust, I see when I run make clean, I get permission denied errors for all generated files. I assume this is because the docker container generated the files? I guess we need to chown after generation?

I think we should avoid running docker as root, let me see if I can take a quick look at this.

@haydentherapper please take a look at #251 and see if it works better (you first need to clean up the existing files of course)

fixed in #473
