[ID-1352] Update TNU version in Dockerfile

[samanehsan]

Use latest version 0.14: https://pypi.org/project/terra-notebook-utils/0.14.0/ which has the following changes

[LizBaldo]

@samanehsan the change looks good, but you need to bump up the version of all of the docker containers appropriately, see CONTRIBUTING.md

[LizBaldo]

Here is a previous PR updating TNU that should be a good baseline #449

[samanehsan]

@LizBaldo, I made the changes you requested

[LizBaldo]

Thanks! Let's see if the tests are passing, I can move this PR along if needed

[samanehsan]

@LizBaldo there are two tests failing but I don't quite understand the errors. Could you take a look?

[LizBaldo]

Yep, I am on it and will move the PR along :)

[LizBaldo]

@samanehsan and @tlangs how critical is the release of TNU 14? As you can see, this PR is getting very unwieldy and I think it is about time that I refactor the base image first, and this whole process frankly. But that might take me a sprint or so, hence delaying the release of TNU further

[samanehsan]

@LizBaldo it's not super urgent so it can wait a sprint or two. The release includes these two changes:

1. Notebooks will tell DrsHub the cloud they are running on to cut down on unnecessary egress costs
2. Notebooks will pass in a "service-name" header so DrsHub can show how many requests are coming from notebooks in our product metrics dashboard (requested by stakeholders)

@samanehsan FYI things are looking almost ready to ship, finally :) If you don't mind giving the sister PR in Leonardo a review that would be awesome, thanks! DataBiosphere/leonardo#4784
