[4.x] Add use to closure to pass in environment condition

[LaurenceRawlings]

I came across this bug when running the Dusk test suite in a new project with Telescope installed. (Local dev environment running on macOS using sail)

Accessing $this inside the closure results in the following error: Target class [env] does not exist.

This can be fixed by calculating whether the environment is local before the filter colsure and passing the value in.

Full error log:
