GLSL Support in Zed

# GLSL GLSL (OpenGL Shading Language) support is available through the [GLSL Extension](https://github.com/zed-industries/zed/tree/main/extensions/glsl/) - Tree-sitter: [theHamsta/tree-sitter-glsl](https://github.com/theHamsta/tree-sitter-glsl) - Language Server: [nolanderc/glsl_analyzer](https://github.com/nolanderc/glsl_analyzer)

Zed provides support for GLSL (OpenGL Shading Language) via the GLSL Extension. This extension leverages external tools to offer a richer development experience. Specifically, it incorporates tree-sitter-glsl, a dedicated tree-sitter grammar, for robust and accurate parsing of GLSL code. Additionally, the extension integrates glsl_analyzer as a language server, enabling features such as code completion, diagnostics (errors and warnings), and other language-specific functionalities to enhance code editing and debugging workflows for GLSL developers within the Zed editor. These tools can be found at their respective GitHub repositories.
