docs: Configure options of jsonschema docs, formatting output

[echoix]

This is a change extracted from the branch now in https://github.com/oxsecurity/megalinter/tree/dev/multi-platform-images (at https://github.com/oxsecurity/megalinter/tree/e223a1a9a0539b3f76da8614ab4b22cb876f3643).
It is to reduce the diff of the branch with main when we will want to merge it.

Proposed Changes

1. Set config option minify to false: the diff between generations will only be the time generated at the end of the file if there are no changes.
2. Set link_to_reused_ref to false: The details of definition will be repeated instead of jumping to somewhere at the other end of the file
3. Set the expand_buttons to false. It is the default value, but a reminder to explore if it pleasant to use. I remember trying it out and didn't like it. The docs of JSON Schema for humans use it here https://coveooss.github.io/json-schema-for-humans/examples/examples_js_default/Configuration.html
