Missing Percona Platform item in Settings

Steps to reproduce:

Navigate to PMM Settings and verify all items present

Actual result:

Last Settings items name is 'Sign up'

Expected result:

Percona Platform item should be present instead of 'Sign up'  that PMM users could understand where to sign up/in.
