Minimal permissions for 'spo sitedesign related' commands

We're adding a new Permissions section to all commands. This section will document the minimal delegated and application permissions required to execute the command.

The goal is to:

• Make it easier to run the CLI with custom app registrations and application permissions.
• Ensure we only document the minimal set of permissions needed.
• Keep documentation consistent by placing the Permissions section right before the Examples section.
• If there are multiple resources, order them alphabetically
• If there are commands that only support one type of auth (like delegated or app-only), we have an example for that as well. E.g. m365 planner tenant settings list - Permissions

Commands in scope

This issue covers the following commands:

• m365 spo sitedesign rights grant
• m365 spo sitedesign rights list
• m365 spo sitedesign rights revoke
• m365 spo sitedesign run list
• m365 spo sitedesign run-status get
• m365 spo sitedesign task get
• m365 spo sitedesign task list
• m365 spo sitedesign task remove

Start with the linked Writing the docs page and minimal-permissions guide, then locate the documentation pages for the eight listed spo sitedesign commands. Add a Permissions section before Examples on each page, documenting only the minimal delegated and application permissions and ordering multiple resources alphabetically; compare the linked Planner examples for the expected format.
