Bazelify this repo and run commands in Bazel

Add the following:

1. `MODULE.bazel` file
2. `BUILD` file
3. Create a `BAZELVERSION` file
4. Update README.md

Use `bazel run` to run the generator inside Dockerfile. Since we are currently using DigitalOcean to host the static website, we will still need to run this in Dockerfile to be built and deployed. Perhaps we can even add a `rules_oci` image that is deployed to a Github Container registry and the Dockerfile just pulls from that base image.

Start by reviewing Dockerfile and the current generator command, then inspect the repository layout to determine where MODULE.bazel, BUILD, and BAZELVERSION belong. Update README.md with the new commands and verify that bazel run executes the generator while the Dockerfile still builds the site for deployment.
