[🚀site]: ts-doc based interactive documentation mechanism

[ala-n]

As a dev ESL consumer, I want to see interactive detailed docs of ESL code.

It is requested to add the ability to insert autogenerated interactive docs sections on the demo pages.

Create a custom shortcut for templates, e.g. {# tsDoc 'src/module/all.ts' #}

• Use passed root file to build TS project tree to parse TS Docs.
• Pare the tree and aggregate Modules (files), Classes, Methods and Properties definition.
• Render documentation using njk template and result definitions.
