Support SARIF as output for redocly lint command.

[Meertman]

Describe the solution you'd like

The Static Analysis Results Interchange Format (SARIF) aims to be an industry standard for the output of static code analysis tools. Therefore it would be very usefull to have the redocly-cli support this format when linting an Open API specification.

CI/CD tools like Azure DevOps support the loading of SARIF reports and as such could easily report the findings of the linting command to an end-user.
