Steps to Reproduce and Observed Behavior

Can be observed for any fn f() ?T in the codebase that return .{.x ..,
but not for fn that have an explicit error(set), ie fn f() error{E}!?T works.

const T = union(enum) { a: u1 };
fn foo() ?T {
    return .{ .a = 1 };
}

Same even if the type is explicitly specified,

const T = union(enum) { a: u1 };
fn foo() ?T {
    return T{ .a = 1 };
}

Cause:

zls/src/analysis.zig

Lines 4494 to 4498 in dfe958e

	if (try analyser.resolveUnwrapErrorUnionType(container_type, .payload)) |unwrapped|
	container_type = unwrapped;
	if (try analyser.resolveOptionalUnwrap(container_type)) |unwrapped|
	container_type = unwrapped;

resolveOptionalUnwrap doesn't do type_vals
E!?T works because resolveUnwrapErrorUnionType returns an 'instance' of ?T

Expected Behavior
