I added some new fields in TimelineSummary in this PR: #95699
Including: '30hz_frame_percentage', '60hz_frame_percentage', '90hz_frame_percentage', '120hz_frame_percentage', 'illegal_refresh_rate_frame_count'.

These fields are not shown in the skia perf tool: https://flutter-flutter-perf.skia.org/e/

I have run the local tests and confirmed that the timeline summary file was generated and it contains the new key-values.

Is there anything that I'm missing for these new fields to be collected by Skia?

@dnfield @flar I heard you two might know how to do it :)

This is blocking #95700
