Bug with transcriber.py - "Unable to extract uploader id"

[wmgillett]

Ran into error "Unable to extract uploader id" with youtube_dl package which seemed widely reported starting 2023-02-16 (issue 31530).
Recommend change to line #5 of code in transcriber.py to fix error

# import youtube_dl
import yt_dlp as youtube_dl

Background:
Bug was apparently related to a change in youtube metadata in Feb 2023 affecting youtube-dl which not yet fixed based on latest commit being in 2021-12-17. I was able to use the forked package yt-dlp as a clean substitute as recommended by this issue #31535 on the youtube-dl repo.
