How to continue using OpenAPI version 3.0.3

[FrederikHD]

With the update from 3.16.4 to 3.17.X, the microprofile-openapi-api version was bumped from 3.1.2 to 4.0.2, which is due to the update from openapi 3.0.3 to 4.0.0.

This update would break a lot of my current project setup like for example my custom OASFilter::filterOpenAPI implementation so my question is can I go back to the old microprofile version and how?
