Attempt to add Python 3.11 support

Python 3.11 has been released as scheduled on October 25, 2022 and this is the first attempt to see how far Airflow (mostly dependencies) are from being ready to officially support 3.11. So far we had to exclude the following dependencies: - [ ] Pyarrow dependency: apache/arrow#14499 - [ ] Google Provider: #27292 and googleapis/python-bigquery#1386 - [ ] Databricks Provider: databricks/databricks-sql-python#59 - [ ] Papermill Provider: nteract/papermill#700 - [ ] Azure Provider: Azure/azure-uamqp-python#334 and Azure/azure-sdk-for-python#27066 - [ ] Apache Beam Provider: apache/beam#23848 - [ ] Snowflake Provider: snowflakedb/snowflake-connector-python#1294 - [ ] JDBC Provider: jpype-project/jpype#1087 - [ ] Hive Provider: cloudera/python-sasl#30 We might decide to release Airflow in 3.11 with those providers disabled in case they are lagging behind eventually, but for the moment we want to work with all the projects in concert to be able to release all providers (Google Provider requires quite a lot of work and likely Google Team stepping up and community helping with migration to latest Goofle cloud libraries)

+Currently in main version of Airflow we run tests in those versions of Python (3.7, 3.8, 3.9, 3.10, 3.11)
 which means that we have to build 8 images (4 CI ones and 4 PROD ones). Yet we run around 12 jobs
 with each of the CI images. That is a lot of time to just build the environment to run. Therefore
 we are utilising ``pull_request_target`` feature of GitHub Actions.
