When we search from VSCE using vsce search <search text>, it returns all VSIDE, ADO extensions too.

Repro steps:

1. Open cmd prompt and enter vsce search test-extension
2. List returns extensions which are ADO and VSIDE extensions.
   

Highlighted Extensions:

1. ADO: https://marketplace.visualstudio.com/items?itemName=westpeaksconsulting.vsts-test-extensions
2. VSIDE: https://marketplace.visualstudio.com/items?itemName=mcferden.TestExtension

Expectations: VSCE should return only vs code extensions.
