Previously, the string representation of masked arrays did not honor global print options such as floatmode, precision, and suppress. This led to inconsistencies between the display of masked and unmasked arrays.
This update addresses the issue by:

Utilizing np.array2string to format the underlying data, ensuring consistency with global print settings.
Replacing masked elements with the masked_print_option string ('--' by default) while preserving formatting for visible elements.
Maintaining support for legacy formatting options, including truncation with ellipsis (...) when legacy='1.13' is set. (FixesBUG: print options not respected for masked arrays. #28685)

Maybe a bit overkill :)
