# This workflow creates and pushes a Git tag to mark a release.
# It also updates the CHANGELOG.md in the root of the repository
# with a list of the changes since previous release.
#
# This is done using a tool called `standard-release`.
# More info here: https://github.com/conventional-changelog/standard-version
