[Website] order of lightline statusbar example

[steffhip]

This is a very minor issue.

The website shows the airline and the lightline statusbar with the applied colors, but the order of the vim modes of the lightline is there "normal","insert","replace","visual" in contrast to the airline order "normal", "insert", "visual", "replace".

To be consistent and easier to compare, the "replace" and "visual" mode should be swapped.
Even the lightline examples of their github page (https://github.com/itchyny/lightline.vim) use always the order "normal", "insert", "visual", "replace". Thus this order should be used.
