chore(rust/sedona-functions): Fix ST_LineInterpolatePoint and ST_LineLocatePoint

[yutannihilation]

I found mismatches of function names during addressing #428. Currently, if a user tries to use ST_LineLocatePoint, they gets a bit confusing error which suggests a wrong function name. ST_LineLocatePoint is anyway not implemented and this probably doesn't happen if it's implemented. So, this pull request doesn't matter much and is mainly for correctness.

> SELECT ST_LineLocatePoint(ST_GeomFromWKT('LINESTRING(38 16, 38 50, 65 50, 66 16, 38 16)'), ST_Point(38, 50));
Error during planning: Invalid function 'st_linelocatepoint'.
Did you mean 'st_line_locate_point'?
