feat: add 'try it out' form

[Shepard2154]

@AceTheCreator, could you take a look at my demo solution and help me with the "try it out" form feature (especially in edge cases)? I believe that together we will be able to do this step by step.

Changes proposed in this pull request:

• created "try it out" form for every operation (pub/sub)
• realized POST method for sending messages from this form
• realized 2 modes for sending messages for more flexibility:
  • Form (inputs generated from schema)
  • Raw JSON (also generated but without any limitations)
• added a checkbox for sending a message to a test/real broker (information for the receiving party)
• added dependencies: '@rjsf/antd' and '@rjsf/validator-ajv8'
