fix(compass-schema-validation): optimises the opening of tab COMPASS-5093

[himanshusinghs]

This PR removes the document count while fetching sample documents as it was not necessary to find the sample of documents matching and not matching the schema

This PR changes the way sample documents are fetched for a provided / modified validator. Changes are summarised below:

• instead of fetching the sample documents for a set / default validator on tab load or on every change, we now provide users with a button to explicitly request a sample document.
• on change of validator, the documents are to be explicitly requested again.
• we now use $sample with a sample size of 10000 as our sample space to match and find documents that could / could not match the set validator.

Just double-checking, COMPASS-5093 mentions two other things: using / making sample smaller and adding a button to explicitly run it instead of doing it automatically, is it something we decided not to do, or will this have a follow up?

[gribnoysup]

Left a few comments. Also the CI failures look legit. You need to reformat your code with prettier and update existing e2e for schema validation (maybe would make sense to add one or two new ones for the functionality you are adding)

@gribnoysup the e2e tests are fixed and I added a few checks for the new behaviour as well. The now failing tests are related to FLE and package test, which as per this discussion is affecting the entire repo.
