usage_description="
Creates a GitHub Release and Git Tag, auto-incrementing the default vYYYY.NN release if one isn't given
Determines the GitHub repository to create a release in from the local checkout from which it is executed,
unless \$GITHUB_OWNER_REPO is set in the environment or '-R <owner>/<repo>' are given as the final args
The first argument is the version, which is recommended to set to vN.N.N eg. v1.0.0 as per semantic versioning standards
If the first argument is 'day' or 'date', will determine the next available release in the format vYYYYMMDD.NN where NN is incremented from 1
If the first argument is 'month', will determine the next available release in the format vYYYYMM.NN
If the first argument is 'year', will determine the next available release in the format vYYYY.NN (the default if no version is specified)
These formats don't have dashes in them like ISO dates so that if you move from YYYY to YYYYMM format or YYYYMMDD format, GitHub will recognize the newer format as the Latest release
If you later return to short format releases of just year or month, GitHub won't detect them as the Latest release (determined via testing).
Requires GitHub CLI to be installed and configured
