Build and commit changes to 'dist' automatically

Instead of requiring that developers keep the 'dist' directory up-to-date,
this process is now automated via a workflow.
Whenever a commit is pushed to 'main' (or a 'release/**' branch), the workflow will
build the application and commit any changes to the 'dist' directory.
