Add option to make migrator 'quiet'

[Explodey54]

Is your feature request related to a problem? Please describe.
When I'm running tests via Jest I would like to drop schema before every test case, but that results in a lot of 'noise' in log output:

console.log
    Processing 'Migration20230222121600InitDb'

      at ../node_modules/@mikro-orm/migrations/Migrator.js:94:45
          at Array.map (<anonymous>)

console.log
    Applied 'Migration20230222121600InitDb'

      at ../node_modules/@mikro-orm/migrations/Migrator.js:95:44
          at Array.map (<anonymous>)

Describe the solution you'd like
Is it possible to add 'quiet' boolean option to migrator config? Something like this:

migrations: {
    quiet: true, // disables all log output from migrator, default: false
},

Maybe better call it silent instead?

The change would be here:

• https://github.com/mikro-orm/mikro-orm/blob/master/packages/migrations/src/Migrator.ts#L118-L122
• https://github.com/mikro-orm/mikro-orm/blob/master/packages/migrations-mongodb/src/Migrator.ts#L86-L90

@B4nan I'd like to take the issue.

Sure, go for it. As mentioned above, I'd call it silent, and don't forget to implement it for both sql and mongo migrators.
