feat: menu items from tags + md extension for Schema Definition (#681)

* add section menus for tags and object description

* bundle and test

* add depth calculation

* add object descriptions to test

* enable operations spacing for operations as well

* bring back section rule, as this could be solved better

* update read/writeonly filter rule to be able to filter both

* add showReadOnly and showWriteOnly options to object-description

* update demo to show use cases

* remove forgotten console.log

* adjust demo test with newly added items

* do the right match with the menu items :/

* chore: refactor + jsxify md tags

* chore: simplify demo spec

* fix: dropdown fixes related to object description
