fix(profile-archival): Add profile archival email text to the email

[lauryndbrown]

Here is a draft for the notice of profile archival.

Subject: Archival of your AMY profile ({ 1st | 2nd | Final} reminder)

Dear { full_name },

You have not logged into your [AMY](https://amy.carpentries.org) account in 3 years.
If you do not log in before { planned date for archival },
your account will be archived according to our
[Privacy Policy](https://docs.carpentries.org/topic_folders/policies/privacy.html).

As a reminder, AMY is the web application that [The Carpentries](https://carpentries.org)
uses to manage information about its community members and events.

To prevent this automated archival, go to <https://amy.carpentries.org>
and log in to your account. You may want to use this opportunity to check
that all your information is up-to-date on your profile.
If you want to archive your profile now, go to <https://amy.carpentries.org>,
log in to your account, and look for the "Archive Button" at the bottom of your profile.

If you have any questions, concerns, or need help logging into your AMY account,
please send us an email at [team@carpentries.org](mailto:team@carpentries.org).

Sincerely,
The Carpentries

for #2047 I think most of the text for the email could be the same, except the first paragraph:

You have not logged into your [AMY](https://amy.carpentries.org) account since we
introduced new terms and conditions. If you do not log in and consent to these
new terms and conditions before { planned date for archival },
your account will be archived according to our 
[Privacy Policy](https://docs.carpentries.org/topic_folders/policies/privacy.html).

the 3rd paragraph should also start with:

To prevent this automated archival, go to <https://amy.carpentries.org>
and log in to your account to approve the new terms and conditions.

I guess users would not be able to archive their profile before consenting, so we might need to add a profile archival button on the consent screen.
