Secondary File to Add Support for the Dark Mode Color Scheme in Notepad++

[MicahKezar]

This pull request introduces dark mode support for the Cisco-IOS-XE-NotepadPlusPlus-Syntax-Highlight project. This change focuses exclusively on syntax highlighting colors to ensure compatibility and readability in the default "Dark Mode" theme in Notepad++ environments.

Key Details:

• Modified color scheme to match the default dark mode background color (#3F3F3F), and to provide additional clarity and contrast for readability.
• No functionality changes have been made beyond the Hex Values.

While I did initially make the changes just for myself, I came to the realization that there may be other people in the same boat I was in—browsing the web looking for Cisco Syntax Highlighting that also supports dark mode functionality.

Lastly, this is my first ever GitHub Fork, and my first ever Pull Request, so hopefully I'm doing it right! I hope this contribution aligns with the goals you initially set when making the project. Let me know if there are any adjustments that need to be made!

Pulling for a brighter (and darker) future, Micah
