[23] Every '/' after third slash in a mark down should be considered to be part of the doc

[jarthana]

This was discussed here: https://github.com/eclipse-jdt/eclipse.jdt.ui/pull/1549/files#r1729935978

And right now, all consecutive slashes after the third are treated as the markdown beginning and omitted from the comment text. But they should really be considered to be the text.
