Fix RegExp 'd' flag compatibility issue in limited_split function (#4514)

- Remove unsupported 'd' flag from RegExp constructor
- Use match.index instead of match.indices for broader compatibility
- Fixes 'Invalid flags: dg' error when test suite delimiters are used
- Resolves issues with gtest-style test names like 'TestSuite.TestCase'
