[GNC] Retrieving quotes is broken since 6/30

[Keith Myers]

 Since I was not getting any help or anwhere searching for solutions, I decided to remove the 5.12 Flatpak version of GnuCash and downgrade to the distro version 5.5.
Lost several source options like financeapi yahoo_web and was left with just AlphaVantage and yahoo_json.
Changed my source to yahoo_json on a whim, it hasn't worked in years, and lo and behold I was able to pull quotes for all my securities. Don't know how long that will last.  Yahoo is always flaky as hell.
So I attribute my prior issue to the Flatpak version which became broken on 6/30.
