Update debian to fix CI while updating Node (facebook#37841)

Summary:
Pull Request resolved: facebook#37841

While bumping node from 16 to 18 in D46583997, Circle CI was failing since it  expects version ">=18" but got "16.20.0".

The job is using a standard `debian:11` container without setting up Node explicitly - so it’s using whatever is built in to that image.

Hence replacing `debian:11` with a later version.

**Changelog:**
[General] [Fixed] - Update debian version
