add a little detail to custom repr method docs (#13945)...

add a little detail to custom repr method docs (#13945) These docs are a bit sparse, so I added a couple details that might help implementers: - explicitly state the return type, rather than only via example - give some examples of PNG, HTML - note that formatters shouldn't be sensitive to other formats related to https://github.com/Textualize/rich/pull/2806 which didn't follow the spec, in part I think because the docs weren't explicit enough about exactly what a formatter should do.
