Update License.txt to MIT

[CyrusNajmabadi]

Oops. Not sure what happened here. This should have been MIT from the start. (it was all created from originally MIT licensed roslyn code).

Fixes #68463

From memory, this was using that license because it uses MS.VS.LSP.Protocol, which has that license. I'm not a lawyer though, so no idea if that means this is an acceptable change or not 😛

Actually, there shouldn't be any license file in this project.

This file and all these properties should be deleted:

<PackageLicenseExpression></PackageLicenseExpression>
<PackageLicenseFile>License.txt</PackageLicenseFile>


  <ItemGroup>
    <None Include="License.txt" PackagePath="" Pack="true" />
  </ItemGroup>

The package will then automatically have the same license as other packages in Roslyn.

That makes sense. I'll change that.

Yeah, that's an oopsy. That license either needs to change, or we need to just stop using it and read/write json directly (or find a helper lib with the right license). Annoying, but doable

I can't find any reference from this project to something named MS.VS.LSP.Protocol. The change suggested by @tmat appears to be the easy solution.

Changes made.
