* feat: add support for Python 3.11

* fix: remove python-snappY

* fastjsonschema: test change due to behavior change in fastjsonschem

* LRU: test

* Removing snappy since it doesnt offer to Python3.11

* Adding support to Python3.11 in the layer for test

* Skipping test

* Skipping test for Python 3.11+
