Current Behavior

I had 168 failing test due to my locale.

failed CommunityToolkit.Maui.UnitTests.Converters.ColorToCmykaStringConverterTests.ColorToCmykaStringConverterValidInputTest(red: 1, green: 0, blue: 0, alpha: 1, expectedResult: "CMYKA(0%,100%,100%,0%,1)") (1ms)
  Assert.Equal() Failure: Values differ
  Expected: CMYKA(0%,100%,100%,0%,1)
  Actual:   CMYKA(0 %,100 %,100 %,0 %,1)

Not all tests for the color conversion fail. Some will generate the test data using my locale and not fail.
Both my locale and the Invariant locale are not creating the correct output as described in the annotation comment and tested for in the hardcoded test data.
The "en-US" locale will produce the correct output.

Expected Behavior

CommunityToolkit.Maui.Core.Extensions.ColorConversionExtensions generate the same output on all locales.
CommunityToolkit.Maui.Core.Extensions.ColorConversionExtensions generate the output described in annotation comment.
The Tests check for the output described in annotation comment using multiple locales.

Steps To Reproduce

1. Set locale to non "en-US" e.g. "de-DE"
2. Run tests
