Consider disallowing backslashes in MyST targets

Describe the problem/need and solution

Context In mdit-py-plugins < 0.3 it backslashes were not allowed in MyST targets. Now they are.

Problem / Idea This is now a valid MyST target:

(myst_target\)=

I think it would be more intuitive and in line with CommonMark if the backslash escape worked, i.e. prevented the target being parsed successfully.

Solution Disallow backslashes in MyST targets.

Benefit Consistency with backslashes in CommonMark.
