Bump minimum python version in pyproject.toml

[robstallman]

Preliminary Checks

• I have searched existing issues for a duplicate issue and I'm sure this is new.
• I have read and followed the docs and still think this is a bug.
• I am certain that this is an issue with shift (not my code or another library such as grid-data-models)

Description

I installed shift from source and created a virtual environment with python version 3.10.4, because I saw that this satisfied the listed minimum version in the pyproject.toml.
During install, the grid-data-models package could not be installed:

ERROR: Could not find a version that satisfies the requirement grid-data-models==2.3.3 (from nrel-shift) (from versions: none)
ERROR: No matching distribution found for grid-data-models==2.3.3

It seems that gdm requires at least python 3.11. Once I created a new virtual environment (this one with Python 3.12.10), all package dependencies were resolved.

Sample Code

git clone https://github.com/NLR-Distribution-Suite/shift.git
cd shift
pyenv virtualenv 3.10.4 shift-env && pyenv local shift-env
pip install -e .
