chore: fix net stubbing flake

Additional details

The net_stubbing test should delay the same amount on every response has been flaky. It typically fails because the delay ends up being slightly over the acceptable buffer of 50 ms.

The other tests in this file handle the buffer slightly differently giving a window of 200 ms by saying the actual delay needs to be within (delay + 100 +/- 100). I updated this test (which is really just testing that each subsequent interception also applies the delay) to do the same and it seems to be passing more consistently. It's worth noting that the delay specified is a "minimum" and not really intended to be super accurate (https://docs.cypress.io/api/commands/intercept#Response-object-properties).
