ExternalDocs URL ignored due to incorrect protocol handling in getSanitizedUrl

[gdec31]

Hello,

I’ve noticed an issue with the handling of the externalDocs URL in the OpenAPI specification.
The generated link is always rendered as:

<a href>Navigate to documentation ↗</a>

Even when a valid URL is provided in the OpenAPI spec, for example:

externalDocs:
  description: "More details here"
  url: http://localhost:8080/doc/more/details

It seems the issue originates from the method:

src/utils/common-utils.js#getSanitizedUrl

The problem is that the URL object returns the protocol with a trailing colon (http: or https:), not http or https.
As a result, the validation fails and the `` attribute ends up empty.

I proposed the fix below :
return url.protocol === 'http:' || url.protocol === 'https:' ? url : '';

The reference:
URL Standard – protocol

"The protocol getter steps are to return this’s URL’s scheme, followed by U+003A (:)."

Thanks for your work, I really appreciate it.
