This patch changes participation condition of bookmark prompt experiment to:

- 1% of new users on Beta/Dev channel, users who create profile after Feb 25(M25) or Mar 1(M26).
- Until Mar 28(M25) or Apr 1(M26)
rather than using variations service.

Checking new user, aka new installation, is as same as
