build: move jest-circus/ facade to jest/

[noomorph]

Description

In this PR, since there is only single integration with jest and jest-circus, and the latter is a default choice for Jest 27, and the only choice for Jest 28 (unless jest-jasmine2 is installed and configured explicitly), I consider it justified to shorten the paths to the user-facing files.

Required changes from the users

In the environment class file:

 const {
   DetoxCircusEnvironment,
   SpecReporter,
   WorkerAssignReporter,
-} = require('detox/runners/jest-circus');
+} = require('detox/runners/jest');

In Jest config:

   "testTimeout": 120000,
-  "reporters": ["detox/runners/jest/streamlineReporter"],
+  "reporters": ["detox/runners/jest/reporter"],
   "verbose": true

Migration flow

As for the attempts to import the files at their old locations, the users will be seeing warnings:

[DEPRECATION] Detox detected an attempt to require a module from an outdated location, please change in your project:
- detox/runners/jest-circus/environment
+ detox/runners/jest/environment

That should enact the migration process smoothly enough.

For features/enhancements:

• I have added/updated the relevant references in the documentation files.
