[10.x] Accept the length of the secret key 🔐

[mahmoudmohamedramadan]

This PR adds more flexibility and difficulty to the merged #49171 PR where we can pass the length of the secret key that we wish to generate via the next artisan command

php artisan down --with-secret=32

This command should generate the next output

I appreciate you extending my PR but I'm not sure I like this change as it would now require the user to define a length for the generated secret which makes it a breaking change. Also, in my opinion, the purpose of --with-secret is to help the user save time by not having to define anything about the secret.

[mahmoudmohamedramadan]

I agree with you, but the purpose of this PR is to add more flexibility to your idea. In addition, it's not a BC as it's not a function that is not used by many projects it is just an option which it's not affect anything, where the developer can pass this option such --with-secret=16 like the default procedure.
