Twenty Twenty: Add privacy policy link to footer

[ryelle]

If you have a privacy policy set, the page should be linked to from the footer of the site. The other bundled themes add this link using the_privacy_policy_link, but Twenty Twenty does not.

In #43715, when the link was added to Twenty Seventeen and earlier, it was dropped next to "Powered by WordPress". I think the same could be done for Twenty Twenty.

Created patch.

This PR will fix the missing Privacy link in the footer.

This Privacy Policy link is also missing in Twenty Twenty One theme. So added in that theme also. added the patch.

@kapilpaul Thanks for the patch! I would rather avoid hiding the Privacy Policy link on smaller screens, so I tried another version.

Changes in 53446.1.diff​:

• copying color settings from @kapilpaul's patch
• adding margin and nowrap for the to-the-top link
• adding a top margin for privacy link on smaller screens, switching to a left margin at 700px wide
• adding flex-wrap to avoid pushing individual elements onto two lines
• unhiding powered-by link at 1000px instead of 700px so the flex-wrap is rarely needed

Patch working as expected

The proposed patch works as expected. See screenshot above and this video recording for smaller screens behavior: ​https://i.gyazo.com/91c70a23ea2b673903a253c350f730d5.mp4

Marking for commit.

Sorry. I omitted to clarify that in my testing above, the Privacy Policy link uses the following title: "Politique de confidentialité".
