      From this version we require NumberLong and NumberDecimal to be constructed from a string. This is a breaking change from the old shell behavior.

      Now: NumberLong("123") and NumberDecimal("123.1") would work, whereas: NumberLong(123) and NumberDecimal(123.1) would throw an exception.

      `NumberLong` is created incorrectly with unsafe integers (> Number.MAX_SAFE_INTEGER)

      The same happens when retrieving a NumberLong which is an unsafe integer, even if was correctly inserted in the database.

      The old shell correctly handles it:

      New shell:

      > db.coll3.insertOne({x: NumberLong("345678654321234561")})
{ acknowledged: 1, insertedId: ObjectId("5f564a3c4f53d376a739e656") }
> db.coll3.find()
[
  {
    _id: ObjectId("5f564a3c4f53d376a739e656"),
    x: NumberLong(345678654321234560)
  }
]

      Old shell:

      > db.coll5.insertOne({int64: NumberLong("345678654321234561")})
{
        "acknowledged" : true,
        "insertedId" : ObjectId("5f564a9284f79fe8de9e7e40")
}
> db.coll5.find()
{ "_id" : ObjectId("5f564a9284f79fe8de9e7e40"), "int64" : NumberLong("345678654321234561") }

      NOTE: looks like is enough to use fromString (converting it before) instead of fromNumber here: https://github.com/mongodb-js/mongosh/blob/e4fb6ea6eae5f5d196038c68301af5bffea57070/packages/shell-api/src/shell-bson.ts#L122
