[ENHANCEMENT] Add support for Zed code editor

[BrunoMoraes-Z]

Is your enhancement request related to a problem? Please describe.
Currently, RobotCode primarily supports Visual Studio Code. With the increasing adoption of the Zed editor, it would be beneficial to extend support to include Zed, enabling its users to utilize RobotCode's functionalities.

Describe the solution you'd like
I propose developing an extension or integration that allows RobotCode to function seamlessly within the Zed editor, offering features such as syntax highlighting, autocompletion, and other capabilities currently available in Visual Studio Code.

Describe alternatives you've considered
An alternative would be to use Zed without RobotCode integration, but this would result in the loss of specific features that enhance productivity when working with Robot Framework.

Additional context
Zed is a high-performance code editor written in Rust, supporting extensions for languages and themes. The Zed community has developed various extensions to support multiple programming languages. Information on developing extensions for Zed can be found in the official documentation.

Additionally, the official Zed extensions repository on GitHub (zed-industries/extensions) contains examples of how other languages have been integrated, which could serve as a reference for developing Robot Framework support in Zed.

Implementing this feature would expand RobotCode's reach and cater to a broader user base that prefers using the Zed editor.
