Handle skipped tests in "Not run" column

[jjomier]

This commit introduces a new notRunSkippedDetailsRegex property to the Project model, allowing users to define regex patterns for not-run test details. A corresponding validation rule is added to ensure the regex is valid. The Build model now includes a method to count not-run tests that do not match the specified patterns, and the GraphQL schema is updated to expose this functionality. Additionally, UI components are modified to display the warning count and adjust test status colors based on the new regex patterns. Tests are also added to verify the new functionality.

I'm conflicted on whether this belongs in CDash, or whether this should be added as a CTest property. I'm leaning towards the latter because it's possible that some projects will want to dynamically set the list of not run test warnings. The build error filter feature removed in #3650 had roughly the same considerations. Any thoughts on this?

It could be in addition to having a "Skipped" test property in CTest. However in CDash we would need a way to handle the display of skipped tests. Where you thinking something else?

@jjomier Is your goal just to differentiate between disabled tests and tests which were "not run" for a different reason?

We want to minimize the number of configuration options if possible, so I'm hesitant to approve this as-is. After discussing this internally, we think the best approach is to just match the text "Disabled" in the details field without it being user-configurable. Thoughts?
