Templates list various months out of date

[EstebenR]

I noticed that collections that were added to the index months ago (like #605 or #595) aren't showing up in the templates website.

For reference, they do appear in the collections website; that's what makes me think it's an issue with the scraping

I wonder if this is an issue with the scraper? It's not apparent to me how often this scraping is done but I think that this shows it's quite a bit out of date 😅

took a look and believe the crawler is failing to parse the index

pr with fix: #644
