Contribution Request: manual installation instructions for Ubuntu

[RationalAnarchist]

I have taken note of the steps needed to install Kapowarr on Ubuntu - would like to contribute to the installation instructions page, if that would be useful. If there are specific distros that you'd like me to validate instructions for, let me know - I can spin them up in azure and figure it out.

Sounds good. Go ahead.

I'll write up a page on how to submit PRs etc for the docs at some point soon (possibly this weekend), just to allow for any future queries. Possibly a "how to contribute to the code/docs" page in general.
