TST: fix test_linear_interpolation_formula_symmetric
The lerp test compared the output of the original and the symmetric
functions by using basic assertion. Double precision errors could
accumulate in a way that the 2 outputs mismatch by epsilon.
For more information on the precision issue, see #22073
Fix: use assert_allclose instead for float comparison.
