feat: Move downloader API repository as a module here

[oSumAtrIX]

Feature description

Right now it is an independent project at https://github.com/ReVanced/revanced-manager-downloader-api. It should be moved into this repository as a Gradle module.

Motivation

The reason it is a separate repository was because it was easier to version independently. However, https://github.com/dhoulb/multi-semantic-release can achieve this in a single repository.

I don't think this issue blocks release, so I have removed it from the release milestone. If anyone has a motivation for why this needs to be done before release, feel free to share it.

When packages are released moving it to this repository might create breaking changes such as the package name in the maven registry. If that's not the case, then the other reason would be that moving shouldn't take more than a couple minutes. I could look into this myself in a couple of minutes

I noticed earlier when I moved the package to the other repo that you can keep using the same package name, so no breaking changes are necessary.

I am not familiar with semantic release, but if you know how to do this then go head 👍
