It's not uncommon for files to have mime types like `image/svg+xml`. The + in there was tripping up the strictly-`@ta` parser for the content-type. Here we change the parser to accept +, and all the other characters that the `@t` parser accepts. This is perhaps a bit overkill, but we primarily care about getting the parsed request to the caller. If any further validation is required, it can happen upstream. Fixes #5282.
