BUG: `RecursionError` with `VaspMaker.input_set_generator.get_input_set`

[Andrew-S-Rosen]

In atomtate2 0.0.14 and pymatgen 2024.5.1, a RecursionError is raised when trying to access .as_dict() or non-existent attributes of VaspMaker.input_set_generator.get_input_set.

from atomate2.vasp.jobs.mp import MPGGARelaxMaker
from pymatgen.core import Structure

s = Structure(
    lattice=[[0, 2.13, 2.13], [2.13, 0, 2.13], [2.13, 2.13, 0]],
    species=["Mg", "O"],
    coords=[[0, 0, 0], [0.5, 0.5, 0.5]],
)
input_set = MPGGARelaxMaker().input_set_generator.get_input_set(s, potcar_spec=True)

input_set.as_dict() # RecursionError

# or...
input_set.fake_attribute_still_crashes # RecursionError

Traceback:
