docs(NODE-6765): sync types for findOneAndUpdate

[forivall]

Description

What is changing?

In #3953, the aggregation pipeline signature was added for updateOne and updateMany, but this was missed for findOneAndUpdate

Is there new documentation needed for these changes?

Documentation is included.

What is the motivation for this change?

The documentation was missing from the node.js driver. The initial motivation is that the downstream mongoose type also need to be updated to allow aggregation pipelines in findOneAndUpdate, but for consistency, these types should be updated first, or at least have this update ready while updating the mongoose types.
