ci(NODE-5424): add CI testing for FLE 6.0 with driver latest

[baileympearson]

Description

What is changing?

To prepare for the 6.0 release and the compatabilty matrix between mongodb-client-encryption and the driver, I added a task to our CI that tests the latest driver changes against mongodb-client-encryption@6.0.0. This task runs for all regular CI runs as a part of the custom csfle tests.

I also pulled in the latest alpha of mongodb-client-encryption for all CI runs except the new variant.

To confirm that the new task was running against the correct version of mongodb-client-encryption, I added the version of mongodb-client-encryption used (if it's available) to the printout before mocha CI runs. This affects all CI runs but I believe this is a useful improvement. Here is an example: https://parsley.mongodb.com/evergreen/mongo_node_driver_next_rhel80_large_Node20_test_4.4_sharded_cluster_patch_51a573fe99506b81c7ab808898eb9eb63f58f600_64d3af041e2d171079fd9bc0_23_08_09_15_21_41/0/task?bookmarks=0,7369&shareLine=545

Is there new documentation needed for these changes?

No.

What is the motivation for this change?

The AC for the JIRA ticket has the entire matrix there, but we have not released a 6.0 driver yet and have no 6.0 branch. Should we move that to another follow up ticket post 6.0 and have this one be driver latest/FLE 6.0 and driver latest/FLE latest?

After https://mongodb.slack.com/archives/GGWBN4ZNK/p1691521646939079, I created the 6.0 branch. We'll just need to rebase it once 6.0 is released.

You can see it's already running CI when libmongocrypt commits. The only task left (and something I had to ask the evergreen team for help for) was limiting which tasks run on the waterfall to only the custom csfle tests.

Ah I can see them running on the 6.x branch now, thanks for the link.
