Include FSharp pre-release packages in the SDK transport package

[mmitche]

• Enable the SDK to publish the stable-preview packages
• Add a pre-release iteration so that previews can be differentiated.
• Remove the version substitution in the shims project. There was no replacement happening.

@baronfel : Can I ask for your feedback/review here, too? Can this affect any direct package consumers (and if positively, should we publish that info?)

[mmitche]

@baronfel let me know what you think.

[baronfel]

I'm not up-to-speed on what the goal is here, so I don't know what kind of feedback I can offer. Is this just getting F# on the same .NET 10-preview-branded package version as many of the other SDK-delivered packages?

[mmitche]

@baronfel Aligning the pre-release labels of the FSharp packages, and aligning with .NET:

https://www.nuget.org/packages/FSharp.Core/#versions-body-tab - Used "beta" without pre-release iteration
https://www.nuget.org/packages/FSharp.Compiler.Service/43.10.100-preview.25277.114 - Used 'preview' without pre-release iteration.

Both would align on 'previewN' now.

[baronfel]

Oh that's perfect.

(Some of these changes were not taken when I merged from dev18 to main, I will investigate why not)

@T-Gro backporting to "main" failed, the patch most likely resulted in conflicts:
