Please highlight do-while and while with double back-ticks.

This is going to be very noisey for codebases that use a do...while macro:

#define MACRO() do { Something(); With(); Multiple(); Statements(); } while (false)

Maybe you should ignore do statements that are in macro expansions as well as potentially do statements with a false condition.

I updated the check according to the last review.

It ignores now do-while statements which are inside a macro and have a false condition. (false condition part was taken from bugprone-terminating-continue)

Tests were added and the check documentation has now a hint about ignoring do-while statements in macros.
