Describe the feature you want to add

allow non http(s) schemes for urls.

on macOS and iOS the deep link mechanism uses a unique identifier as the scheme in an url that is used to deep link into an application. see for example the x-callback-url specification at https://x-callback-url.com/specification/.

these urls are currently not possible to use with bruno as they result in an unsupported protocol error.

Mockups or Images of the feature

a url used to deep link into an application would look something like this:

b4ha://x-callback-url/homekit/0AB904C4-83F7-5715-8624-716E4B33ACBD/B2100B13-7CE8-5549-94BA-EB4F2C366468/AF430181-60B9-5785-99C8-3E40F62028CC?readValue=7&x-source=b4ha-plugin&x-success=streamdeck://plugins/message/b4ha-plugin/2dd5267d16c335cb64996ffb788839bd&x-error=streamdeck://plugins/message/b4ha-plugin/2dd5267d16c335cb64996ffb788839bd&apiKey=9BAD9CE9-8442-4A2B-81A5-5F279B8ACBE6
