Remove once_cell dependency from nu-test-support create. (#8568)

Browse Source 
I was looking where we could remove the usage of once-cell dependency.
As for now, I only found one place. Not a terrible improvement, but at
least, it removes a dependency nu-test-support crate.

Relies on `Mutex::new` constified in Rust 1.63.0
