lowercase order value in dpctl.tensor.copy()

[antonwolfy]

It looks dpctl doesn't properly handle lowercase order value in dpctl.tensor.copy():

import dpctl, dpctl.tensor as dpt

a = dpt.ones(10)

# works with dpt.asarray
dpt.asarray(a, order='c')
# Out: usm_ndarray([1., 1., 1., 1., 1., 1., 1., 1., 1., 1.], dtype=float32)

# but caused an exception with dpt.copy
dpt.copy(a, order='c')
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
Cell In[3], line 1
----> 1 dpt.copy(a, order='c')

File ~/miniconda3/envs/dpnp_dev/lib/python3.9/site-packages/dpctl/tensor/_copy_utils.py:536, in copy(usm_ary, order)
    534         copy_order = "F"
    535 else:

    537         "Unrecognized value of the order keyword. "
    538         "Recognized values are 'A', 'C', 'F', or 'K'"
    539     )
    540 if order == "K":
    541     R = _empty_like_orderK(usm_ary, usm_ary.dtype)

ValueError: Unrecognized value of the order keyword. Recognized values are 'A', 'C', 'F', or 'K'
