This script will apply all Dependabot branches from the remote into a single branch. It makes two assumptions:

• All dependabot branches found on remote are from open PRs (i.e. old dependabot branches are deleted)
• It is running in the root of the repository

This script was written to avoid the pain caused by applying Dependabot PRs one at a time.
