typo fix in symbolic link docs

Hello findutils, I noticed a small typo in the docs for symbolic link handling (which also showed up in a comment) and modified it using a regex. The built output in {prefix}/share/info/find.info appears to pick up the change correctly.

As a side note, I have been working on a library to perform directory traversal and really wished I'd looked at `find` more closely earlier. In particular the discussion of symbolic link handling, stat optimization with -noleaf, and the clever error behavior from -ignore_readdir_race all help to resolve some questions I'd been having difficulty with. The docs section on security implications is also just incredibly well-done and I have mentioned the HTML rendered documentation to others as an example of really effective discussion of safety/security.

Great software!
