marketplace.diff

Add Open VSX default and an env var for marketplace, fix old marketplace

Our old marketplace only supports `serviceUrl` but this causes the marketplace
to be disabled entirely so this moves the template var check to fix that.

This can be tested by setting EXTENSIONS_GALLERY set to:

    '{"serviceUrl": "https://extensions.coder.com/api"}'
