ci: name dispatch workflow differently to default branch push workflow

This allows the status of the two workflows to be distinguished, which
is important for the status badges offered by GitHub (at the moment we
show the status of the "Test" workflow, which means that a broken
dispatch build can show a red status despite the latest master build
succeeding).

Whilst we are at it, re-enable the go:generate of the workflows
themselves.
