Update to 0.20.2

Bump version in the title as another upstream release has been published, link below.

Am I missing something here, isn't this a package that is something of a keystone in the package maintenance toolchain? Couldn't we just cook one up and release it on our end? If someone gives me the thumbs up I'll even try to make something happen on that front myself.

GNU gettext 0.20.2 -
 * tarball: https://ftp.gnu.org/gnu/gettext/gettext-0.20.2.tar.xz
 * signature: https://ftp.gnu.org/gnu/gettext/gettext-0.20.2.tar.xz.sig

it's important, but at the same time the current version works correctly and updates are not only work but they sometime bring back behaviour change or new problems. Is there any specific feature you are wanting from the new version?

If you are wanting to help with the update that would be welcome, read https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=934738 , the maintainer had the new version ready and uploaded but it got rejected requesting to update debian/copyright. He stated he would welcome help doing that update so sounds like the place to start to unblock the new version for Debian and Ubuntu

gettext 21 is available in Ubuntu 21.04 and later https://bugs.launchpad.net/ubuntu/+source/gettext/0.21-3ubuntu2
