BUGFIX: Adjust contributing section to composer changes

[kdambekalns]

When installing for development purposes, --prefer-install=auto needs
to be used since Composer 2.1, see https://getcomposer.org/doc/06-config.md#preferred-install

[mhsdesign]

the --keep-vcs is no longer needed then right?
Or is this for legacy composer?

[albe]

I think it is still needed (https://getcomposer.org/doc/03-cli.md#create-project) though I'm unsure how composer 2.x really behaves for source install. At least it's not stated in the CLI option that it directly correlates with prefer-install

[albe]

Interesting, TIL. Shouldn't we explicitly use source in the case of a development setup though?

Edit: Can we maybe even just add those preferred-install sections to the *-dev-distribution composer.jsons?

That would be the most comfortable ;)

It has nothing to do with the Neos and Framework repository handling, but you might want or need to change something in the development distribution, too. So it's still useful.

Shouldn't we explicitly use source

That's what I tried first, but it downloads everything as source then, even Symfony, Doctrine, … and it creates an error:

$ composer create-project neos/neos-development-distribution neos-development dev-master --prefer-install=source

  [InvalidArgumentException]
  --prefer-source can not be used together with --prefer-install

Only --prefer-source works, but see above. :)

Oh, yes! I didn't even really read that section close enough–I thought it was about ~/.composer/config.json 🙈

D'oh, I didn't know that! Then the old explanation was misleading anyway.

Guess this is fine as a quick fix for now and let's check the composer.json preferred-install section in another PR?

Created issues for the two *-dev-distributions and will merge this as is now :)
