Add installing devel libraries to fedora
Add installing devel libraries to fedora

I followed the troubleshooting and came up with `sudo gem install jekyll` unable to generate the binary file because the development libraries were not installed on my system. Per [fedoraproject.org -- Gems](https://developer.fedoraproject.org/tech/languages/ruby/gems-installation.html) this is necessary to install this. The instructions mirror what is listed on that page, but using `yum` instead of `dnf` - which is understandable because RH and CentOS still use `yum`.
