jsDoc tags are not available from the language service API

The earlier versions (before 2.1) returned all tags (except for @param) when symbol.getDocumentationComment() was called. The new parser is smarter and parses all tags. However they cannot be retrieved by using the public API.

In my case this is needed so that the tags can be analysed by a build script that generates code and documentation. I am using a mixture of standard and custom jsdoc tags that control how a type or property is represented in the documentation.

The typescript.d.ts file does not expose the jsDoc property of nodes. I can do <ts.NodeArray<ts.JSDoc>>(<any>node).jsDoc - this works but I would prefer if this was officially exposed in the API.

Does the API that @minestarks introduced in #12856 address your use case? It adds a new tags property to the return value of getDocumentationComment.
Note that it only exposes unknown tags since getTypeAtLocation uses @returns and @type JSDoc when available.

Yes, it seems to be what I required.
