Local API: Add support for hashtag pages

Pull Request Type

• Feature Implementation

Description

This PR adds support for YouTube hashtag pages when the local api is enabled.

It is not added for Invidious because:

• Invidious does not currently have api support for hashtag pages. See: API: Add hashtag endpoint iv-org/invidious#3692

• The hashtag page is currently not working for invidious. See: Hashtags are broken - "Request contains an invalid argument" iv-org/invidious#3778

Tested https://www.youtube.com/hashtag/pikachu

However I think we need more stuff tested. such as hashtag in video description
Example video with tags in description: https://youtu.be/v6jw6KRIOmw

Also here is screenshot for hashtag view when using IV

Would be cool if you could do something similar to what we do with the channel handles, so that you can search for #shorts without needing to type out the full https://youtube.com/hashtag/shorts URL.

The #shorts thing is just a nice to have, happy to approve without that too.

LGTM, just curious before approval. Is there a reason u didnt add video and channel count?

[absidue]

Probably because YouTube returns it in this single line of text, which is annoying to parse (we need to parse it if we want it to be translatable)

That and invidious currently does not parse that

I'll add that later tonight (if i have time)

Im not sure if i like searching for hashtags like that. With @[insert channel name] its clear u searching for the channel because it is mostly used for that. With hashtags i get other results if i search it normally vs this special hashtag tab.

Lets say im looking for that episode but only remembering finding it on yt using these keywords. On FT u can never find it again.

[ChunkyProgrammer]

Okay, i think i'll remove the hashtag search option.
This is the way youtube does it when you search a hashtag.

Is it possible for u to implement the #search come up in the search results in this PR?

I dont think it's supported by invidious nor youtube.js at the moment
