Remove [Nuget MyGet] color tests

[PyvesB]

Noticed the following test failures:

MyGet [mocked] version (yellow badge)
[ GET /myget/mongodb/v/MongoDB.Driver.Core.json ]

AssertionError: color mismatch: expected 'orange' to equal 'yellow'
    at IcedFrisbyNock._expectField (file:///home/runner/work/shields/shields/core/service-test-runner/icedfrisby-shields.js:85:51)
    at IcedFrisbyNock.<anonymous> (file:///home/runner/work/shields/shields/core/service-test-runner/icedfrisby-shields.js:73:26)

MyGet [mocked] version (pre) (yellow badge)

These were missed out in #10630.

Ultimately, there's no longer any dedicated colour handling for NuGet and MyGet badges, we're just leveraging our standard renderVersionBadge helper logic, which is already tested elsewhere. I suggest we remove these tests.

LGTM but i'm worried about how i did not see this in ci tests at #10630.

It's one of our slightly weird patterns. MyGet badges rely on NuGet code, it's easy to forget the former if you're changing the code of the latter. ;)
