feat: let people turn of active highlighting

[cyai]

Describe the changes you have made:

• Added a new feature to allow users to turn off active line highlighting in code blocks
• Implemented a new CLI argument --no-highlight-active-line (short form: -nhl) to disable active line highlighting
• Modified the OpenInterpreter class to include a highlight_active_line attribute
• Updated the CodeBlock class to respect the highlight_active_line setting
• Adjusted the terminal_interface function to pass the interpreter instance to CodeBlock
• Updated the ROADMAP.md to mark the "Let people turn off the active line highlighting" task as completed

Pre-Submission Checklist (optional but appreciated):

• I have included relevant documentation updates (stored in /docs)
• I have read docs/CONTRIBUTING.md
• I have read docs/ROADMAP.md

OS Tests (optional but appreciated):

• Tested on Windows
• Tested on MacOS
• Tested on Linux

Additional Notes:

This PR adds the ability for users to disable active line highlighting in code blocks, which can be useful for users who prefer a cleaner output or for scenarios where the highlighting might interfere with readability. The feature is disabled by default, maintaining the current behavior, but can be turned off using the new CLI argument.

Please review the changes and let me know if any further modifications or testing are needed.
