Fix broken SSO removal anchor link (#25370)

Fixes a broken anchor link in
`content/manuals/admin/organization/deactivate-account.md`.

The existing link pointed to `#remove-an-organization`, which does not
exist in the target document. Updated it to `#delete-a-connection`,
which points to the correct section for removing an SSO connection.
