chore: remove unnecessary ini_set

Changing gc_maxlifetime cannot have any effect because this configuration option does not exist. There is a configuration option named session.gc_maxlifetime.

I removed the ini_set call because autoconfiguring is error-prone, and the current code could never have worked as intended.
