Current git does not work with yt-dlp 2022.04.08

[auouymous]

642bf7e in #1382 causes the following error when downloading episodes with yt-dlp 2022.04.08:

Traceback (most recent call last):
  File "/home/test/git-gpodder-tmp/src/gpodder/download.py", line 900, in run
    headers, real_url = downloader.retrieve_resume(self.tempname, self.status_updated)
  File "/home/test/git-gpodder-tmp/share/gpodder/extensions/youtube-dl.py", line 109, in retrieve_resume
    opts['paths']['home'], opts['outtmpl']['default']) % info
TypeError: string indices must be integers

I haven't yet determined which version of yt-dlp is required to make #1382 work. This issue either needs to be fixed for older versions of yt-dlp, or gpodder needs to split want_ytdl_version to support separate versions for youtube-dl and yt-dlp, which I already had plans to do. @tpikonen Do you know an easy fix for this or should we require a newer yt-dlp?

It is now possible for yt-dlp to require a different version than youtube-dl. However, yt-dlp 2022.04.08 is currently the latest available for Mint and Ubuntu.

2022.5.18 also fails, and 2022.06.22.1 is the first version that works. #1440 should make gpodder work on both versions.
