Issue:
Allow disabling path uniqueness validation
## Problem statement

In an effort to have the go-swagger toolchain support the [resource name pattern described by Google's AIPs](https://cloud.google.com/apis/design/resource_names), I previously created this [PR](https://github.com/go-openapi/validate/pull/157) against the `go-openapi/validate` repo. I have been using a forking of this repo from 0.30.2 successfully since the PR was merged.

I was attempting to upstream it here but could not work through the errors. Link to patch: https://gist.github.com/dadgar/0ce4b7e49ffd34e9d74813a62f9f5f56

Applying the changes to v0.30.4 works but against `master` I get the following errors when generating the client:

```
$   swagger generate client -f swagger.json -t "$target" -A "cloud-iam" --allow-path-duplicates

```

Here is the generated file: https://gist.github.com/dadgar/67b169e31e6c7707eb78353cf49ca6ad

## Swagger specification
https://gist.github.com/dadgar/29750c3506fad3528fc1a33de8059267

## Steps to reproduce

On a non patched version, simply run the `swagger generate client` against the linked swagger specification.

## Environment
swagger version: 0.31.0  
go version go1.23.1 darwin/arm64


Pull request description:
Fix failing tests
Changes: 
- Fix broken links to OpenAPI-Specification
- revert #3122 

Unfortunately, have to revert #3122 due to the fact that it breaks tests. I guess on merging, due to the issue with tests running on a master branch instead of PR branch (see #3156) we didn't see that the PR tests were broken

Should be rebased after #3156 is merged to see that the tests pass, and only after that, we should merge this PR

Should fix #3142, as it is caused by changes in #3122
