[Doctrine] the reverse-engineering features are deprecated

[stof]

https://symfony.com/doc/current/doctrine/reverse_engineering.html is documenting how to reverse-engineer entities from an existing database. However, this feature of doctrine/orm is deprecated and won't be improved anymore. This should at least be warned on the page, and maybe symfony.com should remove that page entirely.

Do you know the Doctrine version that deprecated this? Or any other official resource from Doctrine confirming that it's deprecated? Thanks! (I can't see that it's deprecated in the Doctrine docs).

Yes: doctrine/DoctrineBundle#1082

Imho, we should just remove the page entirely

Closing as fixed in #16924.
