nls: do not localize open vsx registry

[vince-fugnitto]

What it does

The commit updates the localization of the string Open VSX Registry which was previously translated by Theia.
Given that this is the official name of the service, localization for it's name should not happen.

In other areas we correctly localize the registry:

theia/packages/vsx-registry/src/browser/vsx-extensions-search-bar.tsx

Line 44 in 5aeef6c

placeholder={nls.localize('theia/vsx-registry/searchPlaceholder', 'Search Extensions in {0}', 'Open VSX Registry')}

Related: #11495.

How to test

1. start the application
2. open the extensions-view and search
3. confirm that Open VSX Registry is not localized
4. change languages using Configure Display Language
5. confirm that Open VSX Registry is not localized for different languages
