Corrected typo in function name and doctests. rkf45.py (TheAlgorithms#10518)

* Corrected typo in function name and doctests. rkf45.py There was a mistake in name of function (runge_futta_fehlberg instead of runge_kutta_fehlberg) . I have corrected this in function name and also doctest. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Rename rkf45.py to runge_kutta_fehlberg_45.py * Update runge_kutta_fehlberg_45.py --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Christian Clauss <cclauss@me.com>
