CLI packaged app docs should encourage users to use "--self-contained" argument

### Type of issue

Code doesn't work

### Description

Using the current instructions, users who download a packaged app (even if it is from the store) will run into this issue: https://github.com/dotnet/maui/issues/19763

The documentation should encourage users to use "--self-contained" as part of the CLI command to ensures it works on non-developer PCs without requiring any additional dependencies.
