prelude-rust fails to load due to tree-sitter dependency issue

[ksinkar]

The dependency tree-sitter is no-longer required for emacs29+ (https://emacs-tree-sitter.github.io/). But prelude-rust requires it. I think we need to update prelude-rust to remove that dependency or make it conditional based on the emacs version.

Expected behavior

When I uncomment (require 'prelude-rust) in my personal/prelude-modules.el
Then I expect to enable prelude-rust features without any errors

Actual behavior

Currently I get an error saying that dependency tree-sitter is unavailable.

Steps to reproduce the problem

1. Uncomment (require 'prelude-rust) in my personal/prelude-modules.el
2. Re/Start emacs

Environment & Version information

• Prelude - 460bc16

Emacs version

• GNU Emacs 30.2

Operating system

• Fedora GNU/Linux 42

Yeah, I think we should just remove it. More broadly - we should switch to the built-in rust-ts-mode by default, as it probably provides the best experience these days.
