Create guide for seeking audio resource

[Fyphen1223]

Create a guide for seeking audio resources.

Please describe the changes this PR makes and why it should be merged:
Explain how to seek audio resources with raw discord.js and @discordjs/voice
Many questions about seeking are posted on discord.js guild, and there's no guide about seeking. So I created this.

ESLint is kinda...

[Fyphen1223]

I'm afraid but could you run ESLint one more time? I have fixed all of the error and warning.

[Fyphen1223]

Thanks bro

[Fyphen1223]

k it seems like I've fixed all reviews you sent

[Fyphen1223]

so I have to wait until ESLint approval and merge

[Fyphen1223]

Hey I'm really sorry but could you run ESLint one more time

[Fyphen1223]

Sorry could you re-run ESLint check

(Why ESLint says readability is unnecessary)

[Fyphen1223]

Thank you so much for running so many ESLint check

Personally I'd be against having this as its own article. A more general Popular Topics > prism-media guide would make sense. On its own, this just feels like a guide for FFmpeg; one that already exists at that. This and "Decoding an Opus stream" as examples would cover the only two features of prism-media that realistically would need to be implemented separately from @discordjs/voice as of right now. As a side note, it could also be mentioned that @discordjs/voice already depends on prism-media and presumably shouldn't be installed separately for the same reason one shouldn't install the other subpackages separately.

@ducktrshessami Yeah, that's true enough, but honestly, this will eventually fit in voice section. Because adding content like this in popular topics does not related to discord.js directly. Adding this in voice section (because u know how do you use these things in other part of discord.js bot developing) will be better in my opinion.

I wasn't referring to the "Popular Topics" section of the main guide. I agree that a guide about prism-media is more relevant in the Voice guide. I am simply opposed to this as a standalone article. A new "Popular Topics" section can be added since this isn't directly related to @discordjs/voice. If you do agree I'd definitely like to see this rewritten before being merged.

I see I got it. So you mean, like creating new 'Popular Topics' in voice MD and referring this kind of articles in it?
