`localhost:1234/foo/index.html.html` provokes a 404

Description

Hello! It's reproducable as explain in this ticket: https://github.com/TypeStrong/typedoc/issues/2497#issuecomment-1951427505

It looks like there is a link issue when a file is named index.html.html. Exact same distributable folder is hosted on GH pages, and it works without issues: https://juliancataldo.github.io/og-images-generator/functions/index.html.html

Looks like a very rare edge case.
