upgrade to python 3.11

[drjova]

Currently, in our project, we use Python 3.8, however, Python 3.11 is available which is significantly faster than its predecessors. We need to upgrade it.

Unfortunately, it is not possible to install lxml on macos due to missing wheels for Python > 3.9. There is an issue, opened recently, to add them, we should keep track of it.

another issue is the change in collections: abstract base classes need to be imported from collections.abc instead of collections. This will require updating several dependencies (see for example https://inspirehep.zulipchat.com/#narrow/stream/122199-ops/topic/DESY.20harvest/near/329399196).

Not sure if it will be possible because:

• there's a known bug in pytest for python >= 3.10, we need to upgrade it to version 6.2.5
• then, we get the error from elasticsearch library, because the elasticsearch we currently use support python <3.9
• elasticsearch is locked by invenio search in version <8.0.0, and python >3.9 is supported from the version 8.0.0
