Additional information

(I couldn't find a more appropriate issue form type, so apologies if this is not accurate)

Continuing from cloudflare/workers-sdk#1298 and cloudflare/templates#76, it would be great to update this repo to also use hard tabs for indentation, both in code examples and any other TS/JS.

With the merge of #5013 recently, there wouldn't be any visual change to how code samples are displayed, but when copied out to editors, would include tabs for better default accessibility.

I would very much encourage folks to read through cloudflare/workers-sdk#1298 for all of the reasons why switching to hard tabs for indentation on this repo would be a good thing.

Given the complexity and fast moving nature of this repo, I didn't want to simply submit a PR for this myself (since the diff would be massive), but am happy to do so if requested.
