[Design] Transcriptions Display

The legislature posts recordings of in-person hearings on their website. We are working to transcribe and timestamp the hearings. See dev ticket: #539
There are two aspects to design for:
1. The navigational element (how to people access the transcription)
2. The actual transcription page, and any timestamp feature.

For the navigational element:
- Let's design to incorporate into the future "re-skinned" design. See @jamesvas5307 for details.

For the content:
- Assume we will not be hosting/displaying the video, just the transcript and timestamp
- We should get a timestamp summary similar to what we see here: https://sg001-harmony.sliq.net/00329/Harmony/en/PowerBrowser/PowerBrowserV2/20220607/4/1913#agenda_
- We should also get a full transcript with timestamps for each speaker/speech.
- Perhaps we could design for each "summarized section" expanding into the full transcript?
