Add base64 URL parameter to allow dynamic schemas

[DefCon-007]

Background

Currently, the only way to load schema in the play ground directly via the URL is to use the load or url parameter which requires the schema file to be hosted somewhere and limits the usage.

Sending schema as it is in the URL is not possible hence this change allows the users to send the base64 encoded string of their schema and directly load it in the editor.

Implementation

On load, if the base64 URL parameter is present, we decode its value and send it to the editor as it is to create the preview of corresponding schema automatically.

Screenshots and working

For the example, I used the YAML schema from the example present here and to minify the generated base64 encoded string I converted it to JSON and minified it.

Converting to JSON and minifying is completely optional.

Now, on opening this URL locally, I got the following view.

@DefCon-007 I'm not sure we want to work on this for the playground as studio.asyncapi.com is really the main focus and soon Playground will most probably be archived or something like this. @magicmatatjahu what do you think? and I think you have it in the studio already right?

@DefCon-007 @derberg Exactly, the Studio from far long has a base64 parameter, as well as you can add specifications saved in base64 within the UI. I do not know how long it will take to integrate and automate with DigitalOcean, but when we will release a https://github.com/asyncapi/server-api then we will archive the playground right away :)

@DefCon-007 Hello and sorry for such a late response. We will be archiving the Playground in the near future so I suggest you to use the https://studio.asyncapi.com/ which is the successor of the Playground but with that same and much more capabilities. We also have a Docker Image - https://github.com/asyncapi/studio#using-it-via-docker. We are no longer mainataning the playground, we will be redirecting to the studio. Sorry for problems!
