Release/8.0.2 (#93)

* fix: only attempt to create dir if not yet exists

On self-hosted runners it can happen that an action (docker container) is cached. This leads to the script trying to create the .ssh dir despite it already existing. The action then fails.

* fix: only attempt to create file if it doesn't exist yet

On self-hosted runners it can happen that an action (docker container) is cached, resulting in aborting this script because the know_hosts file already exists. 
This if clause fixes it.
Setting permissions is intentionally outside the if clause because in all cases we want to reset perms.

* fix: reverting printf in favor of echo

Like in commit 2c22263 we are using echo again instead of printf because some runners can't function properly with it.

* chore: 8.0.2

* chore: readme changes
