Script to get GitHub Workflow runs for a given Workflow ID (or name.yaml) via the API

Workflow ID can be either a number (see output of adjacent github_workflows.sh), or the name of the workflow yaml file, with or without the .yaml extension

If no repo arg is given and is inside a git repo then takes determines the repo from the first git remote listed

\$REPO and \$WORKFLOW_ID environment variables are also supported with positional args taking precedence

usage: ${0##*/} <workflow_id> [<repo>]
