Update to latest Flank

[justintuchek]

Update to latest Flank version for correct test time calculations Flank/flank#2364

Ran test locally, we are already running with this through flankVersion and seems to be working well

[runningcode]

There's a few other place to update here as well can you do a find and replace on that version number in the project?

[justintuchek]

Yup!

I think I got everything

There's a few other trailing versions specified for integration + validation test. If you'd like those too I can push up another commit

Tested locally and seem to be passing, fit within the assertions for everything except the test covering non-existent Flank versions (as expected)
