fix(stac-validation): upgrade pystac version and override pystac default stac version (#530)

## What
- STAC metadata validations are currently failing due to a import error
that is corrected in a newer version of pystac
#527.
- The default stac version in the updated pystac is higher than the stac
version of our records so additional configuration was added with a
default value of the current catalog's stac version.

## How tested
The tests are now passing on the github runner:
https://github.com/NASA-IMPACT/veda-backend/actions/runs/17841567081/job/50732312624
