Refactor OC\Server::getAppFetcher

[summersab]

This PR refactors the deprecated method OC\Server::getAppFetcher and replaces it with OC\Server::get(\OC\App\AppStore\Fetcher\AppFetcher::class) throughout the entire NC codebase (excluding ./apps and ./3rdparty).

Additionally, where necessary, the \OC\App\AppStore\Fetcher\AppFetcher class is imported via the use directive.

So, I've never gotten this close to having a PR accepted by the NC team. I see everything is approved and passed, but I need to rebase. If I rebase, does that restart the approval process?

I don't think we need a rebase yet, as this branch is not much behind master.

The failure of cypress seems related to forks. I've seen the same one at #39243 and could not fix it.

Well, I promised nickvergessen that I wouldn't make any new PRs or push code for the rest of the week, so I'll hold off on doing anything until I'm told. :-)

If I convert to draft, will that prevent CI from being triggered if I push updates?

[kesselb]

Don't know, sorry.

Thanks. I know that I became rather well-known in the past 24 hours, so I'd like to do what I can to prevent my newfound popularity from growing any further...
