fix: remove redundant margin property

[Kaciras]

The close icon has an extra padding attribute than the icon on the left, causing them to be at different distances from the border.

This PR increases margin of the left icon, makes the space on both sides equal in width.

Hi @Kaciras, thank you for your PR.

Actually both the icon and the close button have the same horizontal distance (margin) from the container. I consider the padding of the close button being part of the button shape which can be noticed once hovered:

You can see in above screenshots (but also yours) that the margin is clearly the same so there's nothing to "fix".

The "extra" padding you mentioned is something that must be there otherwise it would become difficult clicking/tapping it if too small. On the other hand, this doesn't mean that the space around the status icon (or the icon itself) should be equal or greater than the close button.

That said, I totally get your PR but I think this is more of a subjective preference than something that should be merged and then applied to everyone using this package.

At the end of the day if you think this is wrong you can always "fix" it on your own with one line of CSS. I hope this is clear and thank your for your PR.

I have noticed that you removed a useless line of CSS so I'm happy to merge this if you revert the icon class.
