# This workflow automates the release process.
# It follows the below steps:
#   - Bump the version to the target release version
#   - Run tests and lint
#   - Create and push a branch `release/v<version>` with version bump changes
#   - Open a PR from `release/<version>` branch to `master`
#   - Create and push a release tag with name `v<version>`
