Rollup merge of #110235 - GuillaumeGomez:fix-extend-css, r=notriddle

Fix `--extend-css` option

Fixes #110002.

The file was generated in the wrong folder so I moved it into `static.files` as it made more sense to have there instead of changing the path in the templates.

I also added a GUI test to ensure that this option won't break unexpectedly again.
