Because:
* The release script was filtering updated GitHub issues for the past week rather than past two weeks (our current sprint length).
* The SubPlat team uses the `qa+` and `qa-` labels for QA rather than `needs:qa`
This commit:
* Replaces `A_WEEK_AGO` with `TWO_WEEKS_AGO`.
* Adds another QA section with a different GitHub link for the `qa+` label, since GitHub doesn't support the logical OR operator.
Closes # No ticket on file
- in release.sh: filter out release tags with hyphens, under the
assumption that these are feature branch releases
- add release-feature-branch.sh script that produces a branch & tag
consisting of the last-deployed train with feature branch merged in
