cannot find CLI auth information, broken link in get-your-planet-account.md

[jreiberkyle]

Expected behavior

Authentication information is found where pointed to in get-your-planet-account.md

## Authenticating with the Planet server

After you’ve installed the Planet SDK, you can authenticate with the Planet server as outlined in
the [No-Code CLI Guide](../../cli/cli-guide/#authentication)

Actual behavior (describe the problem)
Clicking that link results in a 404.
