Support running on Linux and MacOS

[the-mentor]

I was trying to use PSModuleDevelopment and it seems like it has a dependency on this module by calling

Invoke-WebRequest 'https://raw.githubusercontent.com/PowershellFrameworkCollective/PSFramework.NuGet/refs/heads/master/bootstrap.ps1' -UseBasicParsing | Invoke-Expression

When I switched the GitHub Action runner to Linux and MacOS it seems to fail.

Thanks in advance
