Convert text/html transcripts into text/vtt (WebVTT)

Problem

text/html can be any valid HTML document, but oftentimes it will have time codes embedded in plain text throughout the HTML.

Example that's entirely text with time codes https://share.transistor.fm/s/0ba4b425/transcript.txt:

[00:00:00] **Cassidy Williams:** Previously on Remotely Interesting... 

[00:00:03] **Jason Lengstorf:** For everyone who's not watching this live Tara just opened her mouth at the end of that joke. 

[00:00:10] **Cassidy Williams:** Hello and welcome to Remotely Interesting.

Example that has nested HTML with time codes https://feeds.buzzsprout.com/1538779/10139859/transcript:

<body>
  <h1><!--block-->Podland 24/02</h1>
  <p><!--block-->[00:00:00]</p>
  <p><!--block-->[00:00:00] Welcome to Podland the last word in podcasting use. It's the 24th of February, 2022. I'm James. Cridlin the editor of pod news.net.</p>
  <p><!--block-->[00:00:08] And I'm Sam Sethi, the MD of river radio, the podcast, first radio station going live on dab on the 1st of March.</p>
</body>

Example that is all test with no time codes (can't do anything special with these) https://share.transistor.fm/s/c4ee7fb9/transcript.txt:

Jeremy:
Hi, everyone. I'm Jeremy Daly.

Rebecca:
And I'm Rebecca Marshburn.

Jeremy:
And this is Serverless Chats. Hey, Rebecca.

Solution

We should try to look for these time codes and create a valid text/vtt document from them. If for whatever reason that isn't possible, the transcript should be rendered as it is today.
