fix: python3.12 build by upgrading pendulum3-beta

pendulum2.x does not support PEP517 and won't build in python3.12, there's a ticket
asking for a release to make it compatible with python 3.12
python-pendulum/pendulum#765

the project maintainers have commented on this ticket to say v2 will no longer get updates
https://github.com/sdispater/pendulum/issues/753\#issuecomment-1739202965

version3 has pre-releases available on github
https://github.com/sdispater/pendulum/releases/tag/3.0.0b1

this commit is now tracking the beta releases to see if there are any issues with
our existing code, and will join back with the stable v3 release as it becomes available

for large portion of it this should address our requirement for python3.12

note that the Dockerfile is update to track patch releases of the python image
