Add WRANGLER_CACHE_DIR and MINIFLARE_CACHE_DIR environment variables

[petebacondarwin]

Summary

Documents two new environment variables introduced in cloudflare/workers-sdk#12466:

• WRANGLER_CACHE_DIR — overrides Wrangler's default cache location (node_modules/.cache/wrangler)
• MINIFLARE_CACHE_DIR — overrides Miniflare's default cf.json cache location (node_modules/.mf)

Both are useful for environments without a traditional node_modules directory, such as Yarn PnP.

Things for reviewer to verify

• Descriptions align with the implementation in workers-sdk#12466
• Whether the example .env section at the bottom of the page should also include these new variables (currently omitted since they are niche/optional)
• Timing: the source PR may not yet be merged
