Fix Typos in Documentation Comments (#1160)

Description:  
This pull request corrects minor spelling errors in documentation
comments within the codebase. Specifically, it fixes the words
"successful" and "consists" in the files `src/sudoers/policy.rs` and
`src/sudoers/tokens.rs`, respectively. No functional code changes were
made; only documentation comments were updated for clarity and
correctness.
