CLI docs reference inbucket instead of local_smtp and mailpit

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

In https://github.com/supabase/cli/pull/5333, the cli was changed to use the local_smtp instead of inbucket in config.toml settings. However, the docs have not been updated.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Go to https://supabase.com/docs/guides/local-development/cli/config#local-development-config
2. See inbucket in the config docs.

Expected behavior

The config should list local_smtp and the reference link to MailPit.
