Publish V2 as a Ubuntu PPA or Ubuntu Snap

**Is your feature request related to a problem? Please describe.**
The current recommended instructions for installing the AWS CLI V2 involve downloading a zip file, unzipping it, and installing it. This seems to be limited, lacking features like bash-completion that are included with the ubuntu-provided `awscli` package.

**Describe the solution you'd like**
A package on Ubuntu's PPA, or other Debian package repository, that provides an `awscli` package and `python3-botocore` package compatible with the existing `awscli` packages in the [ubuntu repositories](https://packages.ubuntu.com/focal/awscli).

**Describe alternatives you've considered**
PyPi support has been [officially discontinued](https://github.com/aws/aws-cli/issues/4947), and the official docker image provides a number of problems around privileges and credentials communication.

**Additional context**
[AWSCLI v1 PPA](https://launchpad.net/ubuntu/+source/awscli)
Apparently [unofficial](https://github.com/aws/aws-cli/issues/5142#issuecomment-698565229) [AWSCLI v1 Snap](https://snapcraft.io/aws-cli) - Well out of date, currently aws-cli/1.15.58
