hide deprecation warning

[adeptofvoltron]

with symfony 6.1 I got such warning:

2023-03-28T12:23:12+02:00 [info] User Deprecated: Method "Symfony\Component\HttpKernel\Bundle\Bundle::build()" might add "void" as a native return type declaration in the future. Do the same in child class "Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle" now to avoid errors or add an explicit @return annotation to suppress this message.

such change repair it

The class is not final, so this is technically a breaking change. You should use a phpdoc annotation instead:

Suggested change

	public function build(ContainerBuilder $container): void
	/** @return void */
	public function build(ContainerBuilder $container)

I also suggest adding @final since 3.3.0 (or 3.4.0 depending on what is the next minor version) on that class

[greg0ire]

The next minor version should be 3.3.0.

[derrabus]

As @greg0ire said, we cannot add a return type to a non-final method in a minor release.

[nicolas-grekas]

@adeptofvoltron up to do the suggested changes?

#494 has been merged.

Thanks. Let's close this one then.
