Docs: Link inline settings when not part of options section (#10499)

## Summary
 
Some contributors have referenced settings in their documentation
without adding the settings to an options section, this has lead to some
rendering issues (#10427). This PR addresses this looking for potential
inline links to settings, cross-checking them with the options sections,
and then linking them anyway if they are not found.

Resolves #10427.

## Test Plan

Manually verified that the correct modifications were made and no docs
were broken.
