Plugin page: Change "plugin/s" text -> "module/s"

Hey,

I am wondering how I would go about changing the text on the plugins page. I am looking to replace any reference to plugin/s (including messages like plugin deactivated etc.) to module/s.

Ideally I could achieve this through a function in a child theme so that the changes are not overwritten upon WordPress updates.

See screenshot here for what I mean:

Thanks.
