Templates list various months out of date

I noticed that collections that were added to the index months ago (like #605 or #595) aren't showing up in the [templates website](https://containers.dev/templates).

For reference, they **do** appear in the [collections website](https://containers.dev/collections); 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 It's not apparent to me how often this scraping is done but I think that this shows it's quite a bit out of date 😅

Compare the templates website with the collections website, checking collections such as #605 and #595 that are missing from the templates listing. Trace how the templates site is scraped or refreshed, determine why those collections are omitted or outdated, and confirm that the affected collections appear after the process is corrected.
