Drop packages defined by Drupal itself from composer.json

[theMusician]

Upon trying to upgrade to Drupal core 9.3.12 composer tossed out a few errors.
docker exec -ti esmero-php bash -c "composer require drupal/core:9.3.12 drupal/core-dev:9.3.12 drupal/core-composer-scaffold:9.3.12 drupal/core-project-message:9.3.12 drupal/core-recommended:9.3.12 -W"

First,
drupal/core-recommended 9.3.11 requires egulias/email-validator 3.1.2 -> found egulias/email-validator[3.1.2] but it conflicts with your root composer.json require (^2.0).

and then after updating that to be ^3.0 manually in composer.json and rerunning the command

drupal/core-recommended 9.3.11 requires typo3/phar-stream-wrapper v3.1.7 -> found typo3/phar-stream-wrapper[v3.1.7] but it conflicts with your root composer.json require (3.1.6).

Fixing those both manually let the command succeed and the upgrade worked.

In conferring on Slack with Diego it seems Drupal itself now declares these packages as dependencies so they are no longer needed in the default composer.json file.

docker exec -ti esmero-php bash -c "composer why egulias/email-validator"

drupal/core           9.3.11     requires  egulias/email-validator (^2.1.22|^3.0)  
symfony/mime          v5.4.7     conflicts egulias/email-validator (~3.0.0)

docker exec -ti esmero-php bash -c "composer why typo3/phar-stream-wrapper"

drupal-composer/drupal-project  -       requires  typo3/phar-stream-wrapper (3.1.7)
drupal/core                     9.3.12  requires  typo3/phar-stream-wrapper (^3.1.3)
drupal/core-recommended         9.3.12  requires  typo3/phar-stream-wrapper (v3.1.7)
