Move Temporal CLI Cloud extension to Public Preview

[lennessyy]

What

• Flip cloudCli from prerelease to publicPreview in src/constants/featureReleaseTypes.js, which updates the ReleaseNoteHeader on /cli/cloud and all 18 cloud command reference pages. Updated the matching prose in setup-cli.mdx.
• Add temporal cloud tabs alongside every tcld command example across 18 Cloud docs pages, with the Temporal CLI as the default tab.

Blocked on two things, hence draft:

• The Homebrew formula in setup-cli.mdx still reads temporalio/prerelease/temporal-cloud. Needs confirmation from the CLI team on whether the tap changes at Public Preview.
• temporal cloud namespace mtls cert-ca list replaces tcld namespace accepted-client-ca list in last-connection-error.mdx, but I could not verify the JSON output shape, so the new tab describes reading the expiry rather than reproducing the jq -r '.[0].notAfter' filter.

Commands were verified against the generated reference pages in docs/cli/command-reference/cloud/ and cross-checked with local --help. Flag names diverge in several places (--id to --key-id, apikey create to create-for-me/create-for-service-account, accepted-client-ca to mtls cert-ca, set-connectivity-rules to connectivity attach/detach).

Left tcld-only where the extension has no equivalent: tcld gen ca/gen leaf (certificates), tcld migration *, and account metrics enable/disable.

docs/cloud/terraform-provider.mdx:87

• After removing the tcld prefix, this names a nonexistent generic apikey create command: Temporal CLI uses apikey create-for-me, while tcld uses apikey create. Name both commands so users know how to obtain the secret.

# replace <your-secret-key> with the "secretKey": output from the apikey create command
