Describe the Bug

When in astro.config.mjs, Astro is configured with build.format 'file', I expect the Astro pages that are output by Astro.glob to have URLs ending in .html. However, the urls are as if build.format is set to directory.

We can fix this by patching GetFileInfo such that it also looks at config.build.format and adds the .html extension if Astro is configured to emit files
