Deprecated use of window padding in waybar `style.css`

[vitorrenansd]

Hi!
First of all, thank you for sharing this Waybar configuration publicly — it's been very helpful!

While using the current style.css configuration, I noticed some warnings when launching Waybar due to deprecated CSS syntax. Here's what shows up in the terminal:

This warning is caused by missing units in the padding declaration under the window class, like this:

To fix this and comply with newer GTK/CSS parsing, simply add the unit explicitly:

This change will eliminate the warnings and ensure better compatibility moving forward.

Let me know if you’d like me to open a pull request with this fix — happy to contribute!
Thanks again for maintaining this project <3
