API Analysis - Stoplight package support

# Description

API Analysis supports spectral as our linting engine.

The following example style guides don't work as we don't support downloading stoplight packages.

How can I get the following example rulesets to work:

extends:
- "@stoplight/spectral-owasp-ruleset"
- "@stoplight/spectral-url-versioning"
rules:
oas3-always-use-https:
given:
- "$.servers[*].url"
severity: error
then:
function: pattern
functionOptions:
match: "(http:\\/\\/localhost)|(https).*"
message: Servers must use the HTTPS protocol except when using localhost
formats:
- oas3
