Add option to write data to a bucket from Curl

There should be an option to write data via the API using curl.

Clicking that option should take the user to a page with examples and their information already filled in, similar to https://v2.docs.influxdata.com/v2.0/write-data/developer-tools/api/#example-api-write-request


Provide user with bucket and token selection first, followed by prefilled copy-able snippet below:

```
curl --request POST \
"http://localhost:8086/api/v2/write?org=YOUR_ORG&bucket=YOUR_BUCKET&precision=ns" \
--header "Authorization: Token YOUR_API_TOKEN" \
--header "Content-Type: text/plain; charset=utf-8" \
--header "Accept: application/json" \
--data-binary '

'
```

Start by locating the existing UI entry point for writing data and the API write-request examples referenced in the issue. Implement the bucket and token selectors with a page that shows a prefilled, copyable curl snippet; done means the option navigates there and the selected values appear in the request.
