Backport: use srvaroa/labeler@v1.12.0 instead of github/issue-labeler (#434)

Switch to using srvaroa/labeler instead of github/issue-labeler to allow
more configuration options.

Add backport labels for dependabot created PRs and for filesync
operations as well.

github/issue-labeler did not provide configuration to add labels based
on PR author or PR branch target or PR branch name.

Switching to allow automatically targeting FileSync operations and
Dependabot Prs to be labeled backport.
