[R2] Implementing partials for R2 Wrangler commands.

[Oxyjun]

Summary

This PR uses partials to handle Wrangler R2 commands page (/workers/wrangler/commands). Specifically:

1. The PR creates a new /partials/workers/wrangler-commands/r2 page, which lists all the R2 commands.
2. The r2 partial page uses AnchorHeading component which allows us to specify the slug (e.g. #r2-bucket-create rather than #create-1.
3. The PR renders the partial file into where the previous R2 Wrangler commands were in /workers/wrangler/commands/ page.
4. The PR carefully stitches + fixes all affected links as a result of this change (because create-2 will now become create-1, and so on) to ensure continuity, even those outside R2. Additionally, all previous links which pointed to R2 now use the updated links. This was done manually to check the context and ensure the correct link is used.

Screenshots (optional)
