Fix alert block migration when invalid disclaimers are flagged
What does this MR do and why?
I happened to notice the the DETAILS alert type had not migrated on this page: https://new.docs.gitlab.com/ci/components/
The problem was that when we log a warning about invalid DISCLAIMER alerts, we were preventing other alerts from being updated. To fix this, we need to not return an error from updateAlerts and instead just log the error from the specific alert that's being migrated.
This MR also adds a temporary JS function so that "Edit this page" links will work for index.md files. This isn't totally related to the migration issue here, but having these working will help for other migration troubleshooting.
