doc_markdown should ignore "CamelCase" #2395
Description
I noticed that the doc_markdown lint is complaining when I write "CamelCase" rather than "camelcase" in my documentation comments and that seems like something that might pop up frequently enough to merit an entry in the default doc_valid_idents setting. (Probably also "camelCase".)
(I also couldn't silence the warning by adding it to my own doc_valid_idents, but that could have been fixed already. At the moment, I don't have time to try updating clippy. That said, I did check the vlaues defined in `conf.rs before submitting this issue.)
