Proposed change

The merge-target check only counted a parent PR listed on the template line, so docs PRs that name their code PR in prose, without a space after the colon, or on an indented line were told to target current. When nothing is listed, it now also counts a PR named anywhere in the description from a code repository home-assistant.io follows. Issues still don't count.

Type of change

• Dependency upgrade
