Merge #2839
2839: Update internal CLI documentation r=curquiza a=jeertmans # Pull Request ## Related issue Fixes #2810 ## What does this PR do? - Make internal CLI documentation match the online one ## Remarks - Scope is limited to `meilisearch/meilisearch-http/src/option.rs`, not the flattened structs: should I also take care of them? - Could not find online docs for `enable_metrics_route` - Max column width wrapping was done by hand, so may not be perfect - I removed the links from the internal doc: should I put them back? ## PR checklist Please check if your PR fulfills the following requirements: - [x] Does this PR fix an existing issue, or have you listed the changes applied in the PR description (and why they are needed)? - [x] Have you read the contributing guidelines? - [x] Have you made sure that the title is accurate and descriptive of the changes?
