feat(devin-lang): add CodeBlockElement class #101

This commit introduces a new class `CodeBlockElement` to the DevInLanguage parser, providing a wrapper for code block elements within text. The class is designed to handle injection host functionality, including updating text and creating literal text escapers. This addition will improve the parsing capabilities of the DevInLanguage plugin, allowing for more accurate and comprehensive processing of code blocks within user input.
