Regexp escape for ! is missing and causes missing images

The ! is not a special regex character? My linter was complaining about it being unnecessarily escaped.

looks like we need some screenshot tests =)

Sorry, there is a mistake in the regex I introduced, but it is not the ! char, it is the following: the regexp currently only copies images with an alt explanatation because I used + instead of * in the regexp:

Current regexp: const htmlImageRE = /!\[.+?\]\((.+?)\)/g;
Should be: const htmlImageRE = /!\[.*?\]\((.+?)\)/g;
