Use TimeInterface for constructor parameter in MemcacheStatisticsController

Attaching patch for composer usage

Good catch, I was going to open the same issue!
Changing issue title and description, to hopefully make it more searchable, and distinguishable in issue lists.

As a follow-up we could add autowire and constructor property promotion.
For now the module still aims to be compatible with Drupal 9.1, I don't remember if we have autowire there.

Automatically closed - issue fixed for 2 weeks with no activity.
