Prep for 2.7.1 (#9790)

* Bump setup.py's ConfigArgParse version (#9784)

I neglected to do this during #9678, so looks like some pip installs
are failing to get the minimum required version.

(cherry picked from commit 02efc8c5ca)

* Fix dnsimple typo (#9787)

Fixes https://github.com/certbot/certbot/issues/9786.

(cherry picked from commit 4e60a0d03a)

* update pinned dependencies (#9788)

This fixes the security alerts those with access can see at https://github.com/certbot/certbot/security/dependabot.

(cherry picked from commit 5849ff73fb)

* update changelog for configargparse (#9789)

I'd like to do a bug fix release for https://github.com/certbot/certbot/issues/9786. If we're doing one, I figure we may as well flag this change from https://github.com/certbot/certbot/pull/9784 too.

(cherry picked from commit 61773be971)
