Website: add maintainer and DRI for ee/fleet-agent-downloader to website custom config. (#43331)

Changes:
- Added the `ee/fleet-agent-downloader` directory to the
`githubRepoDRIByPath` and `githubRepoMaintainersByPath` config values to
the website's custom configuration, and removed
`ee/bulk-operations-dashboard` (which was removed in the PR that added
that directory).
