Use current theme's colors

[ghost]

Would it be possible to add an option to disable any/all custom colour assignments and highlight based on the current syntax theme's keyword colours? I appreciate it's not easy to know how well a given theme's colours will map onto the to-do list context, but it would be a convenient alternative for users of light themes, and those who change theme often.

Thanks for the great extension!

This is currently impossible to implement because of microsoft/vscode#32813.
