Pages doc for Adding Users to Organization has distracting screen shot

[bruce-usab]

The documentation for Cloud.gov Pages for Adding users to organization section for Adding a new user has a screen shot snippet illustrating `Click the plus sign under “Members”' which is not great.

The image highlights the plus sign well enough, but the prominent message "All data for this sandbox organization will be removed in 78 days" is very distracting!

Please replace with something without an alert.

Also, for improved readability, please add a comma to the paragraph under User Acceptance so it would read:

As a new user to the platform<ins>,</ins> you will be sent an invitation via email. The link in the email will take you directly to the cloud.gov login page to authenticate your credentials. You will need to create a cloud.gov account and then use these credentials to login to Pages.

Notes

• Links to rendered page included above
• Path to file on repo is: .... > _pages >pages > documentation > add-user.md
• No slack discussions that I know of

Acceptance Criteria

• [ ] Illustration (screen shot snippet) is replaced
