mise task add should mark the mise config as trusted by default

[hverlin]

docker run -it --rm --entrypoint=/bin/bash jdxcode/mise:latest
root@83c8a5d8dadc:/mise# mkdir proj && cd proj && mise task add my_task  -- echo hello
root@83c8a5d8dadc:/mise/proj# mise task
mise config files in /mise/proj are not trusted. Trust them? Yes
Name     Description
my_task

I would expect mise to not have to trust mise.toml since mise created the file (like for mise use)
