Fix typo in the docs of `CString::from_vec_with_nul`

This PR fixes the sentence "Attempts to converts a Vec<u8> to a CString." in the documentation of the method `CString::from_vec_with_nul` (line 639).

This is because "converts" in that sentence should form a to-infinitive form, and therefore should be in its base form.
