GitHub Action for calculate next nuget version from Github Packages

This GitHub action calls GitHub API https://api.github.com/orgs/${org}/packages/nuget/${packageName}/versions with ${{ secrets.GITHUB_TOKEN }}, to get the latest version and calculate the next version number from inputs such as:

1. main version
2. minor version
3. publish beta or not

Version Calculations

1	0	''	false	1.0.0	first version
1	0	'1.0.1'	true	1.0.2.beta.1	create beta 1 for next patch version
