If you just want to ignore it on this PR, you can add the hyperlint-ignore label to the PR. Future changes won't trigger a Hyperlint review.

Note specifically for link checks, we only check the first 30 links in a file and we cache the results for several hours (for instance, if you just added a page, you might experience this). Our recommendation is to add hyperlint-ignore to the PR to ignore the link check for this PR.

Trying to make our docs more clear because it seems users don't actually go to the api docs to find all the extra customization they can do (https://developers.cloudflare.com/api/resources/browser_rendering/subresources/pdf/)
--> Ended up just bringing up the part about going to API docs to the top of "advanced usage". Also cleaned up a bit what we had already:

1. Endpoint - added section with endpoint clearly shown. Separate from just being within the examples
2. Required fields - added section with what must be included. Wondering whether this is a good place to point them to api docs that will have all the info on customizations they can do
3. Common use cases - added section to just give people ideas of what they can do
4. moved the existing HTML to PDF section to Basic usage and added nesting to the examples
