Privacy policy guide: do not remove the "Suggested text has changed" bubble on saving the policy page

[azaozz]

We went through several iterations before arriving at using mostly "the bubble" and not showing notices/warnings when the suggested text for privacy policy has changed. That made it harder to figure out what's expected and what's updated.

Seems we should be removing the bubble only when the Privacy Policy Guide screen gets loaded, and stop removing it when the privacy policy page gets saved/updated. This seems more logical: the bubble indicates that the guide has some new or updated content and the admin/site owner has to see it to remove the bubble.

In 44063.patch: do not remove the "suggested text has changed" bubble unless the user visits the policy guide.

In 43261:

Privacy: Remove is-dismissible class from notice when privacy info has changed.

The notice isn't dismissible as it only gets removed once you visit the privacy guide, see #44057 and #44063.

Fixes #44065.
