Performed spell check across the rest of code base, and enahnced the yaml paraser code a little (#895)

* Performed spell check across the entire documentation

Thank you once again!

* Performed spell check across the most of code base
Folders been checked:
- agents
- cli
- memory
- project
- tasks
- telemetry
- tools
- translations

* Trying to add a max_token for the agents, so they limited by number of tokens.

* Performed spell check across the rest of code base, and enahnced the yaml paraser code a little

* Small change in the main agent doc

* Improve _save_file method to handle both dict and str inputs

- Add check for dict type input
- Use json.dump for dict serialization
- Convert non-dict inputs to string
- Remove type ignore comments
