https://github.com/void-linux/void-packages/pull/34495

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**
Unfortunately upstream changed quite some things on how to reliably acquire this package - partly due to new licensing terms.
Also the way has been paved for installscripts geared towards "popular" distributions(Ubuntu/Fedora). They now only deploy a downloader to embed the package in the users home directory.
__Edit__: It can not be reliably built from source anymore as it is missing the `secrets` library.
~So meld the generic Linux binary with the Ubuntu one recreating the prior Void distribution of this package(Icons and .desktop are part of the Ubuntu package and can't be hosted elsewhere).
This all is necessary due to a certain company from Redmond, WA forcing Minecraft onto their infrastructure.~
