Nonce does not appear to work on fish shell

[connor4312]

Testing #181522

Other shells are okay, but fish shell did not appear to have a nonce, and prompted for confirmation when rerunning a command

@connor4312 do you have an old shell integration setup in your ~/.config/fish/fish.config?

[connor4312]

I don't think so, these are its contents:

if status is-interactive
    # Commands to run in interactive sessions can go here
end
set -gx VOLTA_HOME "$HOME/.volta"
set -gx PATH "$VOLTA_HOME/bin" $PATH

Code pointer:

vscode/src/vs/workbench/contrib/terminal/browser/media/fish_xdg_data/fish/vendor_conf.d/shellIntegration.fish

Lines 64 to 68 in d70a46b

	# Handle the shell integration nonce
	if set -q VSCODE_NONCE
	set -l __vsc_nonce $VSCODE_NONCE
	set -e VSCODE_NONCE
	end

To verify/reproduce this:

1. Open fish shell, make sure shell integration is enabled
2. Run a command
3. Click the blue circle to the left of the prompt and select Rerun Command, 🐛 it should run immediately and not show a confirmation dialog
