Override jest version used by react-scripts

running tests with coverage flag produces the below errors:

Handlebars: Access has been denied to resolve the property "statements" because it is not an "own property" of its parent.
You can add a runtime option to disable the check or this warning:

This happens to have been yet another breaking change that does not
respect semver versioning for `handlebars` package. This is a package whose
dependecy graph is as follows: react-scripts/jest/jest-cli/istanbul-reporters/handlebars.

We cannot simply remove and add the correct minor version for handlebars to fix this error
, One other alternative would be upgrading the react-scripts version to a version
where they have upgraded all the underlying dependencies all the way to
istanbul-reporters; to a version of the latter that recognizes and is able to work
with the handlebars' changed api. This version of react-scripts does not yet exist
but there is a Pr for it here facebook/create-react-app#8362.

The other alternative and option was to use selective dependency resolution
to override and specify a jest version without needlessy upgrading react-scripts.

This has the disadvantage that we get a few warnings of some configuration options
that jest has deprecated that the current version of react-scripts uses.
