CI: fix labeler syntax

[tvoran]

Labeler job syntax seems to be broken, this might fix it?

Example: https://github.com/hashicorp/web-unified-docs/actions/runs/19843088062/job/56855420138?pr=1419

Before this patch:

web-unified-docs on  main 
❯ cat .github/labeler.yml| yq .
Error: bad file '-': yaml: line 236: did not find expected ',' or ']'

With this patch:

web-unified-docs on  tvoran/VAULT-40510/fix-labeler 
❯ cat .github/labeler.yml| yq .
...

@tvoran Thanks for finding this. I merged PR #1422, which fixed the PR labeler and the issue labeler. I didn't see your message in Slack until after I created my PR.
