New release of 1.6 branch with current mongo-driver

[cdietze]

Is your feature request related to a problem? Please describe.

We have a legacy application that uses morphia 1.6.1.
We need to move away from MongoDB to a SQL database.
So, we're looking to use FerretDB.
FerretDB requires at least MongoDB version 5.0 which is supposed to be fine starting with mongo-driver 3.8.
However, the mongo-driver in version 4.1.1 (used in morphia 1.6.1) still uses some incompatible commands.

Describe the solution you'd like

I'd like a new release of the 1.6 branch that uses the current (4.11.2) version of the mongo-driver.
I already tried it out locally, I can provide a PR if desired.

Describe alternatives you've considered

Upgrading to current morphia needs many adjustments, I would like to make as little changes to our code as possible.
