feat: add dependabot security backport labels (#24484)

Dependabot security update PRs should be backported with the workflow
added in #24025, but today they still rely on someone noticing and
adding the backport label manually.

This updates the dependabot workflow to add the existing backport label
automatically when a newly opened Dependabot PR looks like a security
fix, and it adjusts the Slack notification text so those PRs are called
out explicitly.
