Describe the feature

I've just updated and discovered the new Go test runner feature. It looks great but unfortunately does not work by default on my machine. I am a fish user and I get the following error when running a test:

fish: Variables cannot be bracketed. In fish, please use {$ZED_CUSTOM_GO_P…}.
go test ${ZED_CUSTOM_GO_PACKAGE} -run $ZED_SYMBOL
         ^

⏵ Task `go test ./pkg/tokensvc -run Test_Service_Token` finished successfully
⏵ Command: '/Users/chrisnorman/.nix-profile/bin/fish -i -c `go test ./pkg/tokensvc -run Test_Service_Token`'

As a workaround I'd be very happy to use zsh or bash to execute these tests, I am not sure though which setting to change to switch the shell specifically for the Go tests.

If applicable, add mockups / screenshots to help present your vision of the feature

This should be fixed on Wednesday (in a new Preview build).
