Quotation marks in tvc-guide-description field are not entirely removed

[CSchlipp]

I'm using your docker image to import the Pluto Channels to TvHeadend, thanks for providing it!
During import, I saw some weird data parsed from the m3u. I could also reproduce this parsing error with VLC player.

With V1.2.9, not all quotation marks are removed from the tvc-guide-description field of the m3u file.
Example:
#EXTINF:0 channel-id="chaos-city-de" channel-number="130" tvg-logo="http://images.pluto.tv/channels/60afbad343e3840007164348/colorLogoPNG.png" tvc-guide-art="http://images.pluto.tv/channels/60afbad343e3840007164348/featuredImage.jpg?fill=blur&fit=fill&fm=jpg&h=562&q=75&w=1000" tvc-guide-title="Chaos City" tvc-guide-description="In der US Sitcom Chaos City" ist Chaos vorprogrammiert! Begleitet Michael J. Fox und Charlie Sheen dabei, wie sie den chaotischen Arbeitsalltag in einem New Yorker Rathaus meistern." group-title="Serien", Chaos City
(see " after 'US Sitcom Chaos City')

I suppose this is due to index.js:366 removing only the first occurrence of " and ”, not all.

let guideDescription = channel.summary
        .replace(/(\r\n|\n|\r)/gm, " ")
        .replace('"', "")
        .replace("”", "");

Not a js expert, but this might fix it:

let guideDescription = channel.summary
        .replace(/(\r\n|\n|\r)/gm, " ")
        .replaceAll('"', "")
        .replaceAll("”", "");
