"Installing on an Existing Project" is missing a step

[KableCH]

The docs page for Installing on an Existing Project is missing a step.

The problem

When following the guide, the app container does not start correctly because the dependency runtime/frankenphp-symfony is missing. When using the template directly, this is not the case because the dependency gets installed in here.

My suggestion

Adding the following after step "Re-execute the recipes to update the Docker-related files according to the packages you use":

    Add frankenphp runtime for Symfony:
    
    composer require runtime/frankenphp-symfony

I created pull request #810 for this issue.
Thank you!

Hi @KableCH!

Good catch! The documentation currently describes the runtime/frankenphp-symfony package as optional. Although without this package or without disabling worker mode, the project will not start.

IMO it would make more sense to remove the note about the optionality of the package, moving it to the steps (as you suggest). And the note about disabling worker mode can be supplemented with information about the possibility of removing the runtime/frankenphp-symfony package.

WDYT?

I agree! I pushed a new version. Let me know what you think!
