Save deno install --allow-scripts to deno.jsonc

It would be great if we could save the dependencies which are allowed scripts to deno.jsonc, so that --install-scripts doesn't need to be passed every time.

Also, it would be great if we could save whether we don't want to allow running scripts for some dependency, so that we can get rid of that super annoying warning on every deno install even if the script is not needed for the package to function.
