[DoctrineBundle][Dev] document the profiler profiling sql via `profiling_collect_backtrace`

[94noni]

Ref https://symfony.com/blog/new-in-doctrinebundle-1-11-0#store-backtraces-when-profiling-queries (and a slack on mine on Symfony > doctrine channel asking for such things)

I was unable to find things related to this, what do you think on giving it more visibility on sf doc?

Page where we can add it:

• https://symfony.com/doc/current/reference/configuration/doctrine.html#doctrine-dbal-configuration
• https://symfony.com/doc/current/doctrine.html#configuring-the-database
• other idea?
