Updated marked to 0.5.2

[softbrix]

Now that marked.js has published a new version you can remove the dependency to specific git commit so we can fetch all dependencies from official releases to npmjs.

makred.js merged one more my PR: markedjs/marked#1383

If you are not blocked, let's wait until the new marked release

[softbrix]

I have a working solution for it for now.
Added the following to my package-lock.json in the redoc block:

      "dependencies": {
        "marked": {
          "version": "0.5.2",
          "from": "git+https://github.com/markedjs/marked.git#fb48827236ed3a43e611d2adb3c070ca3f55ed8e"
        }
      }

Lets wait for an update =)

@lpinca says (here) that using commit makes his coworkers maintain dirty hacks so merging this.
Not sure when marked@0.5.3 will be cut.
