fix(pack, publish): default foreground-scripts to true

[ljharb]

Fixes #6816

This fixes a regression in both npm 9 and 10.

An alternative approach to adding a constructor could be, add something in BaseCommand that runs super, and then reads the default from the derived command class, and then sets the default - that way it'd be more declarative. Happy to change to something like that, if preferred.

Check out the save config for how we are overriding the defaultDescription to describe subtleties like this.

[wraithgar]

Let's put a pin in the base command update, since we'd want to include the other things for which the default is different (like save).

Smoke tests will likely need snapshots updated.

[ljharb]

How do I update smoke test snapshots?

[wraithgar]

npm run snap -w smoke-tests

[ljharb]

I've updated the smoke test snapshots but they're still failing.

[lukekarrys]

Smoke tests were failing because they made an assumption that the output of npm pack would only include the name of the resulting tarball which is no longer true with this change.

I fixed this in #7256. Once that lands, this PR can be rebased and should go green.

For reference here's what node . pack now looks like with this PR:

❯ node . pack 2> /dev/null

> npm@10.4.0 prepack
> node . run build -w docs


> @npmcli/docs@1.0.0 build
> node bin/build.js
