- Colordots are generated for colors in inline code, such as `red`, `rgb(255, 0, 124)`, `#ffaabb` and `hsl(124, 52%, 50%)`. However this shouldn't be doon for literal color names as these can be too common assiocated with non-color related stuff _and matches the behavior of some other forge_. - Move the regexes from bluemonday to Forgejo and do the checking ourselves. - Adds unit tests. - Resolves https://codeberg.org/Codeberg/Community/issues/1510
