fix: openapi docs improvements (#1344)

- unify sidebar and content badges for method type
(post/put/create/delete/...)
- render category index pages
- hide next/prev buttons from openapi docs pages
- remove descriptions from generated category index of openapi docs
- add missing syntax highlighting and use custom language order and
labels
- enable docusaurus 3.6 perf optimizations expect SWC loader (not
working with styled components)
