Change behavior of "Schedule Friday" workflow for Skills Issues

### Dependency
- Wait for PR < > to be merged.
- After the above is merged, move this issue to "New issue approval" and add `Ready for Prioritization` label.

### Overview
We need to update the "Schedule Friday" workflow so the bot considers all of a member's activity when deciding whether to leave an activity reminder on their Skills Issue.

### Details
The bot currently labels members as inactive if they haven't updated their Skills Issue in 7-14 days, even when they're active elsewhere. We need to change the bot to check member activity before it applies inactive labels so that active members don't get incorrectly marked as inactive.

### Action Items
- [ ] Check whether a user's Skills Issue has a recent comment. If it doesn't, check whether the bot updated the 'Activity Log' comment on the user's Skills Issue within the last week or last two weeks.
- [ ] Update the code so it checks member activity (not just their Skills Issue) before adding inactive labels.
- [ ] Update the code so the bot applies a new comment to the Skills Issue when the dev has no activity elsewhere.
- [ ] Propose a new bot comment and review it with the team.
