Build documentation failed do I need to change something ?

Charly, thanks for this contribution. The build error is unrelated to your changes (it was a temporary issue in another article).

While we wait to see if this feature is merged in Maker bundle, we'll need to update something in this pull request:

|| is_subclass_of($class, <?= $user_short_name ?>::class; ->|| is_subclass_of(User::class);

You used the code that Maker runs to generate the code, but in the Symfony Docs we should display instead the result of executing that code.

Silly me...

I tought<?= $user_short_name ?> was something generated with/by.rst files

Hum, squashing made unwanted changes... I don't know how to handle this.

I created a new PR :#14304

Which on of these both should be closed ?

No worries. By the way, there's no need to squash changes because the tool we use to merge PRs does that automatically for us. Closed in favor of#14304.
