Fix off-by-one variable names in test__lp_linear_func_galaxy_dict_from

The test sets up galaxy_linear_2 with lp_linear_2 and galaxy_linear_3's
basis with [lp_linear_3, lp_linear_4], but asserted lp_linear_3 and
lp_linear_4 at positions that should be lp_linear_2 and lp_linear_3.
The bug was hidden because GeometryProfile.__eq__ compared __dict__
structurally and parameter-less LightProfileLinear() instances were
all equal to each other.

Exposed by the LightProfileLinear pytree_token-based __eq__ in
PyAutoGalaxy which makes each instance uniquely equal only to itself.
