[mini-browser] add additional 'HtmlHandler' files

Fixes eclipse-theia#6969 This change allows previewing multiple different file types from the `HtmlHandler` endpoint. The supported file types include: - `.html` (previously supported) - `.xhtml` (newly supported) - `.htm` (newly supported) The resetBackground method has also been updated to support the new file types.
