Add a github workflow for Linux based on the swiftlang template (#184)

Test on the Linux distributions that Swiftly currently supports.
Also, test with the latest stable Swift toolchain.

Build libarchive and install it using the shell script.

Remove docker compose files because they are no longer needed.

Fix lint errors.

Remove Amazon Linux 2 because it is not supported with github
actions. Make swiftly releases from RHEL9 since it has the oldest
glibc of the remaining linux distributions.

Add a release build using RHEL9 and add a formatter stage.
