Redirect to the Learn page after updating profile (when prompted by notification)

Summary

Fixes #7362 by updating ProfileEditPage.vue to redirect back to the /learn URL when the user has updated their profile (when prompted by the "Update your profile" notification). See gherkin story:

kolibri/integration_testing/features/learner/learner-profile-update-notification.feature

Lines 22 to 31 in 64f1439

	Scenario: I can go to my profile page from the modal
	Given I see the *update your profile* notification modal
	When I click the *Edit profile* button
	Then I am redirected to the *Edit Profile Page*
	And the *Gender* dropdown is empty
	And the *Birth year* dropdown is empty
	When I fill out the gender and birth year and save (or not)
	And I navigate back to the *Learn* page
	Then the *update your profile* modal does not appear
