Small typo in Ubuntu-LTS-post-install.sh

[atluxity]

There seem to be a simple typo in this sed regex.

Device-Security-Guidance-Configuration-Packs/Linux/UbuntuLTS/Ubuntu-LTS-post-install.sh

Line 160 in 8b096bb

sed -ie '/^DSHELL=/ s/=.*\+/=a/usr\/sbin\/nologin/' /etc/adduser.conf

Somehow there is an "a" there, which does not make sense. A backslash is what makes sense and will make it work.
I tested this on Ubuntu 20.04 LTS and made a quick pull request before I noticed in your guidelines you wanted an issue too.
