Shader uniform vec4 array shows as PackedFloat32Array, breaking future uniforms with the same name.

Issue description

See reproduction steps, as it goes through more thoroughly

Steps to reproduce

1. Make a shader with some working uniforms

   shader_type canvas_item;
   
   uniform vec3 my_array1[4];
   uniform vec3 my_array2[4];
   

   

2. Change one of them to a vec4 array:

   uniform vec4 my_array1[4];

   Array type changes to PackedFloat32Array which kinda makes sense, but the values are still Vec3
   

3. Rename it to my_array without the number and it changes to this:

   Since it's a new variable name, it's pretty much the expected behavior.

   

4. Change it back to a vec3 array:

   Same variable name so the bug happens. The type changes to PackedVector3Array but the values are still floats.
