Fix to remove unneeded spaces around line endings
* Remove initial and final spaces around line endings * Collapse text nodes * Fix to use `''` for empty `alt` instead of `null` * Update dev-dependencies * Update fixtures for new remark formatter (notably, commonmark breaks, better email links, `()` instead of `(<>)` for missing URLs on links and images)
