Support for it.each and updateSnapshot in JEST tests

[mcanivel]

Is your feature request related to a problem? Please describe.
When running jest tests, I'm not able to run it.each tests or update snapshots using the Salesforce Extensions in VS Code. Instead, I need to run the whole test suite for the it.each tests or create my own script to update the snapshots. This just provides more overhead, and having these actions already supported would make testing much easier.

Describe the solution you'd like
For it.each tests, I'd like to be able to run the bundle of it.each without running the whole test suite, and it would be a plus if this was integrated with the existing 'Run Test' action. I'd also like to run these tests from the Testing tab and see their results accordingly. I understand that we can't run individual tests within the it.each bundle, but being able to run the bundle itself, independent from any other test in the suite, would already be super helpful.

For updateSnapshot, I'd like some sort of action available to let me update my snapshots within VS Code.

Describe alternatives you've considered
For it.each tests:

• Running the whole suite

For updateSnapshot:

• Updating my package.json to include a new updateSnapshot script and execute that command line
• Run the updated script from the Debugger section
