[Change request to #27] User password reset

Change request to https://github.com/ita-social-projects/SpaceToStudy-Client/issues/27

Description of a Change request:
Update mockups
Update information on the User Story https://github.com/ita-social-projects/SpaceToStudy-Client/issues/27

Reason for Change:

The discrepancies between the user story https://github.com/ita-social-projects/SpaceToStudy-Client/issues/27 and the actual implementation of the Password reset pop-up should be corrected.

Update:
It is proposed
to change the
"forgot password" to the "Forgot password?" label button,

to add the mockup after the 2nd block
The mockup:

to add the
"The text “Back to Log in” is underlined and highlighted." before 4th paragraph,

to add the mockup after the 6th paragraph
The mockup:

to add the two paragraphs after 8th paragraph
"When a User clicks the close button, then pop-up closes ang a User goes to the last viewed page."
"When a User clicks on the “OK” button, then the system closes popup message and provides him/her to the last viewed page."

Open the linked User Story issue #27 and compare its password-reset popup description with the current implementation and mockups. Update the user story with the requested label, mockup placements, underlined text, and close/OK behavior; done means the documented flow matches the proposed mockups and wording.
