Formerly, developers were directed to install Go and a specific
library dependency on their workstation. We can pull this all into bazel
using bazelbuild/rules_go and bazelbuild/bazel-gazelle.
Now, instead of running a script from a specific directory, the dev
server can be started with a simple "bazel run" command. Or, continue
using the script, which automatically releases the bazel lock before
starting the server.
