Spec as absolute path not absolute URI

[Jmennius]

This should resolve any issues one might have with serving Swagger UI behind a reverse proxy where protocols or ports change, without any additional configuration.

I'll give this a try in a few of my projects and report back.

It works for me in all use cases I can think of, so I'm +1 on merging this.

But before I do, @Jmennius could you please remove the now obsolete proto_port from the codebase? I'll make sure to bump the version and add to release notes that we have a breaking change.

Hey @jschaeff and @vpet98, you were both involved with bringing in proto_port that we are now making obsolete. Can you read through this PR and raise concerns, if you have any, please?

Done. I've reverted the commit almost cleanly (left one blank line fix, hope it was a fix :)).
I understand that you'll write change on github releases yourself?

Thanks!

Thank you for this work and merging in main. Great work !

Sorry for not being very reactive, I was on vacations.
