Description
When caching following URLs:

1. http://wilson.com/en-us/blog (no extension)
2. http://wilson.com/en-us/blog/basketball/events/wilson-takes-paris-storm-recap-nba-paris-game-2024
   Request 1. will create local file <cache_folder>/en-us/blog
   Then, caching 2. (or any other /en-us/blog/** path) will fail as it cannot create folder <cache_folder>/en-us/blog (as the path already exists as a file)

To Reproduce

1. Start the AEM importer aem import --cache /tmp/cache
2. In the importer UI, import http://wilson.com/en-us/blog
3. Check /tmp/cache/en-us/blog file got created
4. Import http://wilson.com/en-us/blog/basketball/events/wilson-takes-paris-storm-recap-nba-paris-game-2024
   => Notice the cached file is not created + error message in the CLI log

Expected behavior
The CLI should handle such case.
