Fixed validation of requirements in route description

[vodevel]

See #1873

Example

#[Route('route/{id}', requirements: ['id' =>  '\d+'])]

Now Swagger UI allows any {id} that contains at least one digit (eg. x1 or "1"). Whereas in Symfony Routing allows {id} that consists only of digits. To be sure, run

bin/console route:match /route/x1
# Error: almost matches but requirement for "id" does not match (\d+)

bin/console route:match /route/11
# Success: Path Regex   | {^/route/(?P<id>\d+)$}sDu  

See also https://github.com/symfony/routing/blob/6.2/RouteCompiler.php#L301

Therefore, a wrapper has been added to fully comply with the requirements.
