add @WithGradleVersionsLessThan, @WithGradleVersionsGreaterThan, @WithGradleVersionsLessThanOrEqualTo and @WithGradleVersionsGreaterThanOrEqualTo

Before this PR

When writing tests that need to run on specific Gradle version ranges (e.g., only pre-8.0 versions, or 8.5+), users had to either:

1. Use @WithOnlyGradleVersions and manually list every version in the range
2. Add conditional logic inside the test itself

This is tedious and error-prone, especially as new Gradle versions are added to the test matrix.

After this PR

Adds four new annotations for filtering tests by Gradle version comparisons:

• @WithGradleVersionsLessThan("8.0") - run only on versions < 8.0
• @WithGradleVersionsGreaterThan("7.6") - run only on versions > 7.6
• @WithGradleVersionsLessThanOrEqualTo("8.5") - run only on versions <= 8.5
• @WithGradleVersionsGreaterThanOrEqualTo("8.0") - run only on versions >= 8.0

These can be combined for version ranges:

@Test
@WithGradleVersionsGreaterThanOrEqualTo("8.0")
@WithGradleVersionsLessThan("9.0")
void test_gradle_8_only(GradleInvoker gradle, RootProject project) {
    // Runs on Gradle 8.x versions only
}

Version comparison uses Gradle's built-in GradleVersion class for proper semantic version ordering.

==COMMIT_MSG==
Add version comparison annotations for Gradle version filtering

Adds @WithGradleVersionsLessThan, @WithGradleVersionsGreaterThan,
@WithGradleVersionsLessThanOrEqualTo, and @WithGradleVersionsGreaterThanOrEqualTo
annotations that filter tests to run only on Gradle versions matching the comparison.

Annotations can be combined for version ranges (e.g., >= 8.0 AND < 9.0).

Possible downsides?

None - this is purely additive functionality.
