Update a dependency in DEPS

Update a dependency in DEPS

A Github Actions workflow has been created that makes the process of auto bumping DEPS easier.

You can run it by visiting https://github.com/brave/brave-core/actions/workflows/update-dep.yml and clicking the Run workflow button on the top-right.

You can also run it from cli by: gh workflow run update-dep.yml [-f dep=vendor/web-discovery-project] [-f ref=commit-hash] If ref is not given, we will try to use the latest commmit (tip) of a branch called master or main
