Duplicate assembly 'System.Collections.Immutable.FSR.dll' with different versions detected

Yo, seems like both `System.Collections.Immutable.FSR.dll` and `System.Collections.Immutable.dll` identify as `System.Collections.Immutable`. Not sure if vendor one can be removed, or FSR one can be internally renamed (and usages updated if needed).

Also not sure it's a problem, just popped up in Unity's Assembly loading/analysis debug log

> Duplicate assembly 'System.Collections.Immutable.FSR.dll' with different versions detected, using 'Packages/com.handzlikchris.fastscriptreload/Plugins/Roslyn/2021+/System.Collections.Immutable.FSR.dll, AssemblyName=System.Collections.Immutable, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' and ignoring 'Packages/com.handzlikchris.fastscriptreload/Plugins/Roslyn/2021+/System.Collections.Immutable.dll, AssemblyName=System.Collections.Immutable, Version=1.2.3.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.[MODES] ModeService[none].Initialize

Take care :tada:

Start by inspecting the Unity assembly-loading debug log and the two files under Packages/com.handzlikchris.fastscriptreload/Plugins/Roslyn/2021+: System.Collections.Immutable.FSR.dll and System.Collections.Immutable.dll. Compare their assembly identities and usages in the plugin, then determine whether the duplicate warning affects FastScriptReload. Done means the warning is either resolved safely or documented as harmless with supporting evidence.
