Description

Pino documentation states that in order to turn off the logging for a certain route, one should set `{logLevel: 'silent'} in the route options.

This works well, however it doesn't play nice with Typescript. It happens because logLevel property in RouteShorthandOptions interface uses an alias for pino.Level, instead of pino.LevelWithSilent as its type -

Steps to Reproduce

fastify.get('/your-route', { logLevel: 'silent' }, (request, reply) => {
  reply.send({ hello: 'world' })
})

will give you TS2322: Type '"silent"' is not assignable to type 'Level | undefined'.

Expected Behavior

no TS error should occur
