[Lock] remove duplicated announcing of automatic scoping - #22526

Thanks Ayyoub. You are right that this was weird. However, the full solution was a bit different and we did some changes in 0c25c8e:

• Normal contents (like the ..note should never mention any Symfony version)
• The versionadded directive should be the only one that mentions when something was added to or removed from Symfony

We do this because whenever Symfony releases a new major version (e.g. Symfony 9.0 (https://symfony.com/releases/9.0) in July 2028), we delete all the versionadded directives automatically:

• Since versionadded only contains the mention to the Symfony version number and never real docs, it's safe to remove them.
• Since the rest of contents never mention the Symfony version, we don't have to update any contents when a new Symfony version releases
