fragments_fromstring should return a List

[nwalters512]

Per the lxml source code, fragments_fromstring should return a List:

https://github.com/lxml/lxml/blob/d5593c118856d3eba1eef181e3e0c666ded11f35/src/lxml/html/__init__.py#L770-L772

However, the type stubs here declare it as returning an _Element:

lxml-stubs/lxml-stubs/html/__init__.pyi

Lines 75 to 81 in 0a9b609

	def fragments_fromstring(
	html: "_AnyStr",
	no_leading_text: bool = ...,
	base_url: str = ...,
	parser: "_BaseParser" = ...,
	**kw
	) -> "_Element": ...
