annotationlib: `ref.evaluate(format=Format.FORWARDREF)` not evaluating global generics with undefined params

[dr-carlos]

Bug report

Bug description:

from typing import Sequence
from annotationlib import Format, get_annotations

class A:
    x: fails[Sequence, undef]
    y: fails[list, undef]
    z: works[list, list]

x_anno = get_annotations(A, format=Format.FORWARDREF)["x"]
y_anno = get_annotations(A, format=Format.FORWARDREF)["y"]
z_anno = get_annotations(A, format=Format.FORWARDREF)["z"]

fails = dict
works = dict

print(x_anno.evaluate(format=Format.FORWARDREF))
print(y_anno.evaluate(format=Format.FORWARDREF))
print(z_anno.evaluate(format=Format.FORWARDREF))

This should print:

dict[Sequence, undef]
dict[list, undef]
dict[list, list]

Instead, the following is outputted:

ForwardRef('fails[__annotationlib_name_1__, undef]', is_class=True, owner=<class '__main__.A'>)
ForwardRef('fails[__annotationlib_name_1__, undef]', is_class=True, owner=<class '__main__.A'>)
dict[list, list]

The issue seems to be that the globals are not considered when creating the _StringifierDict in this code path (whereas builtins and locals are):
