You are installing a file-publishing mechanism called upload-to-issue in this
repository. Read this whole brief before you touch anything.
A person or an agent pushes a branch named upload-to-issue/<N>, where <N> is an
issue or pull request number. The branch holds one or more files at its root. A GitHub
Actions workflow on that branch uploads each file to a storage destination, comments
the links on issue/PR <N>, then deletes the branch.
