Replace the ESLint built-in valid-jsdoc rule with the eslint-plugin-jsdoc plugin

[EdJoPaTo]

ESLint drops support for JSDoc rules they should be replaces with eslint-plugin-jsdoc anyway. see: https://eslint.org/blog/2018/11/jsdoc-end-of-life

I'm going wait until ESLint actually removes the rule. For every plugin I add, it adds more maintenance work for me, keeping up with new rules, reporting issues, etc.

It also seems like the plugin is missing things from the valid-jsdoc rule: gajus/eslint-plugin-jsdoc#107
