openapi-types: adding support for openapi 3.1

[wszydlak]

According to:

• https://www.openapis.org/blog/2021/02/16/migrating-from-openapi-3-0-to-3-1-0
• https://www.openapis.org/blog/2021/02/18/openapi-specification-3-1-released
• https://spec.openapis.org/oas/v3.1.0

I've prepared types for OpenApi 3.1 support. Don't know if we would like to keep OA 3.0 types, so i decided to keep under another namespace.

I've changed types mostly by extending types from OA 3.0, but in many cases there are some changes.

Looking for some feedback from You, I know this also need to write some tests (I will write as soon as possible, or maybe someone would like to help?)

• [X] I only have 1 commit.
• [X] My commit is prefixed with the relevant package (e.g. express-openapi: fixing something) Note: You can use the bin/commit script to automate this.
• [ ] I have added tests.
• [x] I'm using the latest code from the master branch and there are no conflicts on my branch.
• [X] I have added a suffix to my commit message that will close any existing issue my PR addresses (e.g. openapi-jsonschema-parameters: Adding examples to the validation keywords (fixes #455)).
• [ ] My tests pass locally.
• [X] I have run linting against my code.

I re-checked and made some changes. Also moved 3.0 namespace to nested namespace, so for old types we can use OpenAPIV3.V30.Document

I don't see any tests in openapi-types, so don't know how do we event want to test those types.

@jsdevel it would be nice if you could check this PR

@jsdevel I hope PR can pass through this time. We need to generate documentation from a specific version 3.1. Also, thanks @wszydlak for the nice effort.
