Suggestion: Provide a list of dependencies in a "Before you start" section of the Installation page

Hello there, greetings!

I think that adding a list of dependencies for both back-end and front-end in a new "Before you start" section of the Installation page could be very helpful, to avoid having conflicts when installing the package.

It could also be handy to add a command to check if the installation would work, like so:

composer require package1:version1 package2:version2 --dry-run

or

npm install package1@version1 package2@version2 --dry-run

Thank you!
