Add tutorials for cloudflare workers with wrangler

Add a tutorial on deploying to Cloudflare Workers using wrangler.

Thanks for the contribution. A few blockers before this can land:

1. Line 85: [esbuild tutorial](https://www.google.com/search?q=/examples/esbuild/) is a Google search URL — likely an LLM artifact. There's also no /examples/esbuild/ page in this repo. Either link to a real internal page or drop the sentence.
2. The new page isn't registered in examples/_data.ts. The existing CF tutorial sits at line 557 (/examples/cloudflare_workers_tutorial/); add a sibling entry for /examples/cloudflare_workers_wrangler_tutorial/ so it shows in the sidebar.
3. deno wrangler dev / deno wrangler types (tasks at lines 52–54) and deno --allow-env --allow-run wrangler deploy (line 51) aren't valid invocations — Deno has no wrangler subcommand. After deno add npm:wrangler, run it via deno run -A npm:wrangler dev (or use the binary that deno install exposes). Please fix these so a reader running deno task dev actually starts Wrangler.
4. Line 76: satisfies ExportHandler<Env> — Cloudflare's exported type is ExportedHandler<Env> (with the "ed"). Can you confirm this compiles against the cf-typegen output?

• nit: dev and start tasks (lines 52–53) are duplicates — pick one.
• nit: title doesn't follow docs: ... lowercase format the repo uses, but maintainer can squash.

@fibibot
Thank you for taking the time to review this! I am very sorry that some paragraphs were overlooked during the process of translating my text into English.
I will request another review after making corrections based on the other points you mentioned. I am sorry, and thank you!

Thanks for confirming. The existing request-changes review still applies until a new commit updates the invalid Google link, the missing sidebar entry, the Wrangler command invocations, and ExportedHandler<Env> type; I’ll re-review the changed revision when it lands.

Several examples on this page are not runnable yet, and the new tutorial is not wired into the examples navigation.

1. "dev": "deno wrangler dev" / "cf-typegen": "deno wrangler types" use a nonexistent Deno subcommand; on Deno 2.7.14 this resolves wrangler as a local file and exits Module not found ".../wrangler". Use deno run -A npm:wrangler ... or document the node_modules/.bin path that makes the binary available.
2. } satisfies ExportHandler<Env>; should be ExportedHandler<Env>; cf-typegen emits Cloudflare's ExportedHandler, so the copied sample will not type-check as written.
3. [esbuild tutorial](https://www.google.com/search?q=/examples/esbuild/) is a search URL, and there is no /examples/esbuild/ page in this repo. Link to a real page or remove the sentence.
4. /examples/cloudflare_workers_wrangler_tutorial/ is not added to examples/_data.ts, so the page will not show in the examples sidebar next to the existing Cloudflare Workers tutorial.
