Support Tenor's v2 API

[locness3]

It appears that Tenor have deprecated the V1 API that this extension is using in favour of a V2; it is not possible to register for a V1 API Key anymore.

I recently made some changes supporting tenor v2, you can use this branch instead - https://github.com/noahjames404/flarum-ext-gifs/tree/tenor-v2

@noahjames404 you can always make a PR for me to review and merge 😇.

Actually nvm, I was planning to support both since people may not have moved yet. Looks like your code migrates it completely.

@therealsujitk v1 was already deprecated on my region so I migrated everything to v2 instead.

@noahjames404 alright then, can you create a PR whenever possible? I'll take a look.
