Refactor RepoActionView.vue, add ::group:: support (#32713)

1. make it able to "force reload", then the previous pending request
won't block the new request
2. make it support `::group::`
3. add some TS types (but there are still many variables untyped, this
PR is large enough, the remaining types could be added in the future)
