Switch from jsdoc-parse to jsdoc-to-markdown

[gotnone]

The jsdoc-parse version is quite old and has some vulnerabilities in its dependencies. The author of jsdoc-parse, after bumping the version to 2.x, recommends using the getTemplateData() function from his package jsdoc-to-markdown instead of the lower level jsdocParse(). This patch replaces 'jsdocParse()' with a call to jsdoc2md.getTemplateData().

I am not sure that this code is 100% correct. Occasionally, when calling toJsonSchema() to generate a JSON schema and return it as an object, the underlying jsdoc2md.getTemplateData() does not resolve and it neither rejects nor throws an error.

I experimented with getTemplateDataSync() and did not have any problems with my example jsdoc file, but I wanted to retain the async nature of toJsonSchema(). I am not entirely convinced that this is a problem with @75lb 's code, more than likely it is operator error on my part.

My workaround is to use something similar to promiseTimeout() to reject and then retry the parse. FWIW I am currently testing in an electron environment.
