feat(devin-lang): add support for Markdown plugin integration and completion provider implementation. #101

This commit introduces support for the Markdown plugin by including it as a dependency in the plugin configuration. Additionally, it lays the foundation for a completion provider by implementing the `CodeLanguageProvider` class, which is a crucial component for providing context-aware code completion suggestions within the IDE. The completion provider is currently a work in progress, with the `TODO` comment indicating that further development is required to implement the actual completion logic.
