Adds the ability to configure the UI through configuration:

nelmio_api_doc:
  html_config:
    assets_mode: bundle
    redocly_config:
      expandResponses: '200,201'
      hideDownloadButton: true
    swagger_ui_config:
      deepLinking: true

This configuration option should more generic to potentially allow more options in the future, this also aligns this new configuration option with the DumpCommand --html-config option and also let's it serve as a potential way to customize the default value for --html-config.

Thank you! I was planning on doing it myself but I was not able to find the time for it yet :) I will try and have a look at everything later today if my time allows it
