Maintenance: Upgrade Outdated Python Style

[RHammond2]

This PR is the result of running pyupgrade --py38-plus against the codebase to identify lingering pre-3.8 language standards.

TODO prior to moving out of draft stage:

• Incorporate develop following at least PRs Bug Fix: Update Pandas Offsets Usage #271, Bug Fix: Pandas loc-chaining #272, Maintenance: Complete Adoption of project.toml #273, and Enhancement: Reduce Example Runtimes #266
• Run the plotting examples to ensure the updated f-string format annotations still work following the pyupgrade styling
