Youtube channels with spaces in name will not work

[blksh3p]

There is an issue with the youtube extraction regex that stops if there is a space in channel name. Eg

https://www.youtube.com/watch?v=kU9y8rKCe3w&ab_channel=Well%2BGood

will not work,

the issue is with regex
(?:https?://)?(?:www.)?(?:(?:youtu.be/)|(?:youtube.com)/(?:v/|u/\w/|embed/|watch))(?:(?:?v=)?([^#&?=]))?((?:[?&]\w=\w*)*)```

that should be rewritten to
(?:https?://)?(?:www.)?(?:(?:youtu.be/)|(?:youtube.com)/(?:v/|u/\w/|embed/|watch))(?:(?:?v=)?([^#&?=]))?((?:[?&]\w=[\w%+]))
