Add support for RouterOS Script

[Albatrosicks]

This is a scripting language for MikroTik's routing equipment.
Here are several example projects for this language from other editors:

• https://github.com/dokai/routeros-conf
• https://github.com/Kentzo/MikrotikScript
• https://github.com/ReK42/sublime-mikrotik-routeros
• https://github.com/tikoci/lsp-routeros-ts

Personally, I expect at least syntax highlighting support for .rsc files for ROS 6 and ROS 7 script versions

Definitely not happening in core Zed, so will close this discussion in this repository.

But maybe someone can crate an extension, hence worth creating an issue in https://github.com/zed-industries/extensions
