Capture app and migration version (#20458)

* Add AppMetadataController so current and previous application and migration version can be captured in sentry

* Add currentAppVersion, previousAppVersion, previousMigrationVersion, currentMigrationVersion to SENTRY_OBJECT

* Update app/scripts/controllers/app-metadata.ts

* Update app/scripts/controllers/app-metadata.ts

* Update app/scripts/controllers/app-metadata.ts

Co-authored-by: Mark Stacey <markjstacey@gmail.com>

* Fix types

* Add tests for app-metadata.test.ts

* Lint fixes

* Modify loadStateFromPersistence to return the whole versionData object, so that the migration version can be passed to the metamask-controller on instantiation

* Remove reference to implementation details in test descriptions in app/scripts/controllers/app-metadata.test.ts

* Reset all mocks afterEach in AppMetadataController

* Refactor AppMetadataController to be passed version instead of calling platform.version directly (for ease of unit testing the MetaMask Controller)

* Make maybeUpdateAppVersion and maybeUpdateMigrationVersion private, and remove unit tests of those specific functions
