Add kotlin coroutine driver to MongoDB's dependency management

[nenros]

Currently to keep same version of coroutine driver we need to make nasty trick

val mongodbVersion: String? = dependencyManagement.importedProperties["mongodb.version"]

dependencies {
    implementation("org.mongodb:mongodb-driver-kotlin-coroutine:${mongodbVersion}")
    implementation("org.mongodb:bson-kotlin:${mongodbVersion}")
}

It would be much easier to keep that version in spring bom.

mongodb-driver-kotlin-coroutine has been introduced in MongoDB 4.10.0 so one can argue it's an oversight in our dependency management. If we want to fix this, we could add the missing bits up to Spring Boot 3.3.x.

Flagging for team attention to see what the rest of the team thinks.

I would be really gratefull if it can be added in next 3.3.x release
