fix: getting started commands with jbang

Fixing this based on quarkusio/quarkus#22723

The issue here is that if you are BRAND NEW user you don't have
trusted the location quarkusio jbang catalog fetches its jars from.
i.e. you have no `~/.jbang/trusted-sources.json`

Thus if you run this command first:
`curl -Ls https://sh.jbang.dev | bash -s - app install --fresh --force quarkus@quarkusio`

jbang will ask you to trust BUT curl via pipe result in no tty being available, i.e. user
can not say/answer yes; thus until jbang 0.86 we delayed that question until
you actually try and run the installed script - but as seen in #22723
that confuses people too.

So in jbang 0.87 I made it so `jbang app install` will ask you for trust,
but it does not fix the first install as here you still don't have a tty to ask user.

Thus this PR adds explicit call for trust. Then it works for initial user too.
