Flag unix support for ModuleFast in PowerShell Gallery with tags #81

Seems ModuleFast runs fine on Linux.

It's not currently possible to know what platforms ModuleFast supports just by looking in PowerShell Gallery.

• https://www.powershellgallery.com/packages/ModuleFast
  • https://www.powershellgallery.com/api/v2/Packages()?$filter=Id%20eq%20%27ModuleFast%27%20and%20IsLatestVersion%20and%20IsPrerelease%20eq%20false
• https://pwsh.gallery/ModuleFast/index.json

Supporting PowerShell Core is not a guarantee that it runs on Unix (Linux, MacOS).

How to flag that you support a given platform does not seem to be more standardized than adding tags. Ref:

• 2024-12-30 Standardize how to flag OS support in PowerShell Gallery packages, PSResourceGet and in PowerShell itself PowerShell/PowerShell#24723
• 2024-02-18 Find-PSResource should tell what platforms a resource supports PowerShell/PSResourceGet#1570

So, add "Unix", "Linux" and "Mac" as tags? Like PSResourceGet does it:

• https://www.powershellgallery.com/packages/Microsoft.PowerShell.PSResourceGet
• https://github.com/PowerShell/PSResourceGet/blob/f1b3cf7af01eab5ef2e5b3cef7b910a4a4b1e7b4/src/Microsoft.PowerShell.PSResourceGet.psd1#L49-L54
