Minetest: Remove the '$' symbols in the bash snippets in the README file.

It's annoying when you copypaste it especially when it automatically inserts a newline and runs the command. Am I wrong? Do they serve some other purpose? I see this on so many repos.

Sorry I am too dumb to program C++ so all I contribute to is README files and documentation.

every contribution is useful, especially in docs :)

FYI: This notation originates from the notation of regular users ($) and root (#) in the terminal. Example:

user@hostname:~$ sudo -i
[sudo] ....
root@hostname:~#

It's a typical notation used in linux documentation, it can be quite annoying when selecting text.
