Strip alias from a data_type chain - this function should be
used *after* aliases are resolved (see resolve_aliases fn):

Loops through given data type chain (unwraps types), replaces
first alias with underlying type, and then terminates.

Note: Stops on encountering the first alias as it assumes
intermediate aliases are already removed.

Args:
    data_type (DataType): The target DataType chain to strip.
Return:
    None
