This pull request adds support for testing binary uploads to Anaconda Cloud using different tokens and channels based on the branch name. It modifies the `.github/workflows/_binary-upload.yml` workflow and several other workflows that use the `.github/templates/upload.yml.j2` template. It also adds a new secret variable `conda-pytorchbot-token-test` to store the test token.
