Remove: Pingvin-Share

[MickLesk]

✍️ Description

https://github.com/stonith404/pingvin-share

After much consideration, I've chosen to focus my limited time and energy on my other project, As a solo developer, I've found it difficult to actively maintain multiple open source projects with the care and attention they deserve.
If you're interested in continuing this work through a fork, I'd be happy to link to it here in the README.
Thanks to all the contributors and users who have supported Pingvin Share over the years :)

-> The project files (pingvin.sh and pingvin-install.sh) will be removed by the end of the year at the latest to ensure a clean switchover.
