Inappropriate typo suggestion for argument of option

[KalleOlaviNiemitalo]

In --option=argument syntax, if the argument is not accepted by the option, then typo correction can suggest replacing the argument with a different option. That should not happen when they are connected by an equals sign.

Demo

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="System.CommandLine" Version="2.0.0-beta4.22272.1" />
  </ItemGroup>

</Project>

using System.CommandLine;

return new RootCommand().Invoke(args);

$ dotnet run -- --version=h-
'h-' was not matched. Did you mean one of the following?
-h
1.0.0

A secondary bug here is that the version middleware outputs the version even after typo correction has notified the user about the invalid syntax.
