Install ServiceHub x64 vsix for integration test

[genlu]

Fixing integration-corehost CI. Broken by the change that added a new vsix

[sharwell]

❤️ provided roslyn-integration-corehost passes

OK, I could locally repro the same error as in integration CI (with int.Preview build)

However, when using a VS build (from this validation insertion PR) that ships this servicehub.x64 vsix, it worked

PS C:\Program Files\Microsoft Visual Studio\2022\Preview> C:\Users\gel\Downloads\RoslynTools.VSIXExpInstaller.1.1.0-beta3.23252.1\tools\VSIXExpInstaller.exe /rootSuffix:RoslynDev /vsInstallDir:"C:\Program Files\Microsoft Visual Studio\2022\Preview" "C:\Users\gel\roslyn\artifacts\VSSetup\Debug\Roslyn.VisualStudio.ServiceHub.Setup.x64.vsix"
"C:\Users\gel\Downloads\RoslynTools.VSIXExpInstaller.1.1.0-beta3.23252.1\tools\VSIXExpInstaller.exe" /rootSuffix:RoslynDev "/vsInstallDir:C:\Program Files\Microsoft Visual Studio\2022\Preview" C:\Users\gel\roslyn\artifacts\VSSetup\Debug\Roslyn.VisualStudio.ServiceHub.Setup.x64.vsix
  Running as Admin.
  en-US
  Installing local extension (C:\Users\gel\roslyn\artifacts\VSSetup\Debug\Roslyn.VisualStudio.ServiceHub.Setup.x64.vsix) over global extension (C:\PROGRAM FILES\MICROSOFT VISUAL STUDIO\2022\PREVIEW\COMMON7\IDE\COMMONEXTENSIONS\MICROSOFT\VBCSHARP\LANGUAGESERVICES\CORE\)
    The extension was succesfully installed locally: 'C:\USERS\GEL\APPDATA\LOCAL\MICROSOFT\VISUALSTUDIO\17.0_46CC08F2ROSLYNDEV\EXTENSIONS\E05WXOO2.CTS\'

So it seems the issue is Roslyn.VisualStudio.ServiceHub.Setup.x64.vsix is not installed as part of the VS already?

Convert to a draft PR until I figure out what's going on

integration test passed on core host.
