CI: Update GitHub actions environments and used actions

Updates the used actions to their latest versions, and update the images to the -latest tags.

This currently means Ubuntu will use 20.04 LTS (and soon 22.04 LTS) and macOS will use macOS 12.

Also adds a workflow_dispatch trigger to the main workflow (the others already have it).
