build-docker-image-manual.yml

# This manually-triggered workflow builds OpenFAST docker images for the linux/amd64 and linux/aarch64 architectures for
# the specified git ref (this can be a branch, tag, or commit hash). The image is tagged with the given tag and pushed
# to the `nrel/openfast` repository. The build cache is stored in GitHub actions.
