* Rework 'make generate-images' - Remove external dependencies and replace it with a node script that does does the same. - Move detail removal from gitea-sm.png to favicon.png - Remove favicon.ico and its generation, it is unused and we already serve favicon.png in its place. Fixes: https://github.com/go-gitea/gitea/issues/12314 * use proper centering value for preserveAspectRatio * fix lint * use fabric * better linting fix * fix typo * mention detail-remove class in docsfor-closed-social
