Fix 0 view count on related videos section

[shiny-comic]

This PR fixes #5403.

Tested, works fine!
Youtube doesn't seem to return viewCountText and it only returns shortViewCountText now.

Edit: Since viewCountText is not returned anymore, we should add a comment about it above this variable (or just delete the variable) but I'm not sure what compact renderer is:

invidious/src/invidious/videos/parser.cr

Lines 28 to 31 in 89c8b1b

	# "4,088,033 views", only available on compact renderer
	# and when video is not a livestream
	view_count = related.dig?("viewCountText", "simpleText")
	.try &.as_s.gsub(/\D/, "")

@SamantazFox There is any background about that line that was written 3 years ago?

Its either for an old Innertube structure which never got removed in Invidious or just how the view count is stored in the Innertube responses of some other InnerTube client different than the ones that Invidious currently uses

@SamantazFox There is any background about that line that was written 3 years ago?

It was introduced in #2856, when Youtube switched to the compactVideoRenderer for related videos (in the next endpoint response).

If that's not relevant anymore, that can be removed.
