During compilation, we had the following warning which is now fixed
```
==> restarter
Compiling 1 file (.ex)
warning: Logger.__do_log__/4 defined in application :logger is used by the current application but the current application does not depend on :logger. To fix this, you must do one of:
1. If :logger is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs
2. If :logger is a dependency, make sure it is listed under "def deps" in your mix.exs
3. In case you don't want to add a requirement to :logger, you may optionally skip this warning by adding [xref: [exclude: [Logger]]] to your "def project" in mix.exs

This was done by floatingghost as part of a bigger commit in Akkoma.
See <37ae047e16/lib/pleroma/application.ex (L83)>.

How it fails?

This is based on me setting one up, but I kept it general with mostly linking to other documentation.
The idea is that to just provide some Pleroma-specific info, maybe give some pointers, and point to the right (external) docs.
It used a timer to sleep.
But time also goes on when doing other things, so depending on hardware, the timings could be off.
I slightly changed the tests so we still test what we functionally want.
Instead of waiting until the cache expires I now have a function to expire the test and use that.
That means we're not testing any more if the cache really expires after a certain amount of time,
but that's the responsability of the dependency imo, so shouldn't be a problem.
I also changed `Pleroma.Web.Endpoint, :http, :ip` to `127.0.0.1` because that's the setting people typically have,
and I see no reason to do it differently.
Especially since it's an exernal ip, which may come over as weird or suspicious to people.
The previous pictures were labeled as public domain, but are actually a collage of pictures under other licenses.
I now replaced them with a jpeg of simply a white pixel.
