This adapts an approach taken by the Gradle actions in order to
generate the dist files on the main branch rather than having
every contributor need to generate them. (In fact, people will no
longer be able to submit PRs with the dist files updated). This
change is important because the current approach means that
people encounter merge conflicts all the time and will need to
keep regenerating the dist files in order to land their change.
