Fix parsing Resource type as value type of a Dictionary

[Synzorasize]

Fixes #100889.

A line was forgotten, so I added it. I do not believe it affects anything else as the scope is specifically for this use case.

Hopefully this gets merged soon. My friend needs to finish his godot project for skool

It would also be nice to add tests for typed arrays and dictionaries, somewhere here:

godot/tests/core/variant/test_variant.h

Line 1740 in aa65940

TEST_CASE("[Variant] Writer and parser array") {

godot/tests/core/variant/test_variant.h

Line 1790 in aa65940

TEST_CASE("[Variant] Writer and parser dictionary") {

Also please correct the commit message.

Should this be added in this PR, or a future one? I suppose the Dictionary one fits here, since this PR fixes a bug that slipped through as a result of not having this check, but it may be out of scope for the Array one.

I feel like the code could potentially be cleaned up/optimized, though I am not sure what usecase the parentheses after Resource is usually for, as I haven't recalled seeing them before in tres or tscn files. I have only seen usecases of ExtResource and SubResource with parentheses. Other than that, I think it might be best to merge this for now.

Looking at surrounding code, that seems to make sense, but I'm not expert.

Good eye!
