`list-prs-for-file` could include the PR title #4056

GitHub has a way to automatically fetch the titles of linked issues by adding a few attributes: https://github.com/sindresorhus/refined-github/blob/397c46f6bf078c887a6d83518967e969e737cad1/source/github-helpers/dom-formatters.ts#L36-L44

We could add them to this dropdown:

URL: https://github.com/sindresorhus/refined-github/blob/main/readme.md

We probably shouldn't add this when it's a single linked file because that already has a title that explains what the link means ("This file is touched by this PR")
