Highlight BiDi chars on the frontend

What does this MR do and why?

In https://gitlab.com/gitlab-org/security/gitlab/-/merge_requests/1862 we added a mechanism on the backend to wrap/highlight BiDi characters on the backend.

This MR Highlights BiDi chars in the refactored source viewer.

This list of characters to be highlighted is based on the paper that was published on the vulnerability and researching packages like this one.
