Add influxdb3 CLI command reference pages for InfluxDB 3 Cloud

Cloud pages don't exist yet at the paths below, so [`content/influxdb3/cloud/request-information.md`](https://github.com/influxdata/docs-v2/blob/master/content/influxdb3/cloud/request-information.md) aliases them to a "Request more information" page. Publish the real content and remove the alias.

Closest existing equivalent to source from: `/influxdb3/enterprise/reference/cli/influxdb3/`

## Aliased paths

- [ ] `/influxdb3/cloud/reference/cli/influxdb3/create/database/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/create/table/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/delete/database/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/delete/table/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/query/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/show/databases/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/update/database/`
- [ ] `/influxdb3/cloud/reference/cli/influxdb3/write/`

## Anchors the new content must provide

Shared content deep-links to these fragments. They're currently faked as hidden ``s in `request-information.md`; remove each span once the real heading exists.

- `#options`

## Done when

- [ ] Content is published (or the linking shared content is gated for Cloud)
- [ ] The alias is removed from `request-information.md`
- [ ] Any hidden anchor ``s that belonged to these paths are removed
- [ ] `link-checker` passes

Part of #7391.

Compare the existing pages under /influxdb3/enterprise/reference/cli/influxdb3/ with the eight aliased Cloud paths listed in the issue. Start with content/influxdb3/cloud/request-information.md, remove the aliases and hidden option anchors when real headings exist, then run link-checker. Done means all eight Cloud pages are published, shared links work, and link-checker passes.
