Removing private SSH key

[oudeismetis]

I noticed you had commited a private ssh key to your repo.

"I know. It was intentional."
Sorry to bother you then. Feel free to ignore this PR.
You know you can also secure private data while keeping it under source control.

"I didn't notice. What is this file? Is it a problem?"
This can be a very bad thing

"I keep accidentally typing git add ., any way I can prevent that from being an issue?"
There are a couple of steps you should take immediately:

1. Avoid commands like git add . and git add *. It's better to be more explicit when you can.
2. Assume your key is compromised. Unassociate it from any accounts you are using it for and generate a new key.
3. Store your keys in a location outside of your project.
4. Use a .gitignore file to prevent accidental commits of certain files.

Github also has a page about how to remove sensitive data from a repo.

Hope this PR finds you well
