internal/graphicsdriver/opengl/gl: fixes DeleteVertexArrays removing …

…entry from textures instead of vertexArrays value store in webgl driver (#3125)

This is just what appears to be a typo in the WebGL driver that is deleting the mapping between a uint32 ID and a
JavaScript value for vertexArrays from the value store for the textures instead. This seems like it would potentially
cause a crash if the numbers aligned.
