[BUGFIX] Use correct `typo3/cms-styleguide` for main

Branching in `typo3/cms-styleguide` have been done
some time after the core branched versions. That
led to an invalid state in composer.json/lock and
further issues, for example when using the composer
lock file update command: `composer update --lock`

This now leads to weird constellations. Therefore,
we now require the correct version of styleguide
to break that invalid cycle and have correct version
in the `composer.json` and `composer.lock` files.

Used command(s):

> composer require --dev "typo3/cms-styleguide":"~13.0@dev"
