Fixes issue #134023 where alpha API warnings were being logged
when binary version (1.34.1) and emulation version (1.34) differed
only in patch version.

The issue was in api_enablement.go where the version comparison
was using EqualTo() which compares all version components including
patch versions. The fix changes the comparison to only check
major.minor versions using version.MajorMinor().

Changes:
- Modified version comparison logic in ApplyTo() method to only
  compare major.minor versions, not patch versions
- Added comprehensive test cases to verify the fix works correctly
- Tests confirm that warnings are still logged for different
  major/minor versions but not for different patch versions

This prevents spurious warnings when emulation version is set to
major.minor (e.g., 1.34) and binary version includes patch (e.g., 1.34.1).
