sdk/basyx/aas/adapter/xml/xml_serialization.py: `lang_string_set_to_xml()` called without `tag` parameter

[moritzsommer]

Currently, object_to_xml_element() calls lang_string_set_to_xml() without setting the tag parameter.

Lines 934 to 935 in e043960

	elif isinstance(obj, model.LangStringSet):
	serialization_func = lang_string_set_to_xml

Unlike the other ..._to_xml() methods, it is not possible for lang_string_set_to_xml() to provide a default value for the tag parameter, as the tag is always different. Therefore, we should develop a method that can differentiate between all possible values of the tag parameter and set the correct one in lang_string_set_to_xml() if it is not specified (using param=None).

Technically, this is a valid bug. Technically as well, these lines of code are only for completeness and should never be executed.

I would suggest to therefore delete them, but I'm open for discussing other options.
