When adding pages from wikis to include reference documentation in Obsidian, the MediaWikiMirrorApplication::getRenderUrl method doesn't properly substitute spaces with underscores.

If we configure the workspace with underscores in the page title, the title rendering retains the underscores.

The best solution is to allow the getRenderUrl method to automatically handle the substitution of spaces with underscores. This would ensure that we can control the use of underscores when desired, without manual adjustments.
