perf: use kareem 3.3.0 re: mongoosejs/kareem#45

[vkarpov15]

Summary

Pulling in changes from mongoosejs/kareem#45 - consistently trims 5-10% off of the saveSimple benchmark. Not a lot, but we're getting much closer to matching the MongoDB Node driver.

Before:

{
  "Average mongoose save time ms": 1.03,
  "Average driver insertOne time ms": 0.71
}

After:

{
  "Average mongoose save time ms": 0.98,
  "Average driver insertOne time ms": 0.73
}

Pull request overview

Updates Mongoose’s Kareem dependency to pull in upstream performance improvements (mongoosejs/kareem#45), aiming to reduce overhead in common save flows and improve benchmark parity with the MongoDB Node driver.

Changes:

• Bump kareem dependency from 3.2.0 to 3.3.0.

Aside from some CI failing likely due to outdated github npm cache on some runners (notarget kareem@3.3.0), this LGTM.
