Version 6.11 results in oas3-server-variables error for relative server URL and variable substitution

[philipnbbc]

Describe the bug Docker image stoplight/spectral:6.11 is returning a oas3-server-variables error for a relative URL server that has a variable substitution.

To Reproduce Given spec.yaml, an OpenAPI document (only servers: -url is important and the rest is to avoid errors/warnings):

openapi: 3.1.0
info:
  title: title
  description: description
  version: version
  contact:
    name: name
    email: email
servers:
  - url: /example/{version}
    variables:
      version:
        default: version
paths:
  /:
    get:
      description: description
      operationId: get
      tags:
        - tag
      responses:
        '200':
          description: description
tags:
  - name: tag
    description: description

and spectral.yaml config file,

extends: spectral:oas
rules: {}

Run docker run --rm -v $PWD:/data -w /data stoplight/spectral:6.11 lint spec.yaml and it returns:

/data/spec.yaml
 11:15  error  oas3-server-variables  A few substitutions of server variables resulted in invalid URLs: /example/version  servers[0].variables

Expected behavior It should pass like it does for version 6.10 (No results with a severity of 'error' found!).

Note that it does pass for version 6.11 if the /{version} is removed from the url or if the url is an absolute URL.

Environment Docker image stoplight/spectral version 6.11
