fix: Accept ValueError for JAX backend tolist fallback (#1746)

* In JAX v0.2.27 the error raised for trying to pass a sequence as a list
includes a ValueError

>>> import jax
>>> import jax.numpy as jnp
>>> jax.__version__
'0.2.27'
>>> jnp.asarray([[1, 2], 3, [4]])
TypeError: int() argument must be a string, a bytes-like object or a number, not 'list'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/.../site-packages/jax/_src/numpy/lax_numpy.py", line 3648, in asarray
    return array(a, dtype=dtype, copy=False, order=order)
  File "/.../site-packages/jax/_src/numpy/lax_numpy.py", line 3606, in array
    out = np.array(object, dtype=dtype, ndmin=ndmin, copy=False)
ValueError: setting an array element with a sequence.

To handle this, also accept ValueError as a valid exception when falling back
to list.
