docs: fix server lookup instructions in publishing guide (#411)

The publishing guide incorrectly suggested users could verify their
server by directly accessing `/servers/{server-name}` or
`/v0/servers/{server-name}`, but the API only supports:

1. **Search by name**: `GET /v0/servers?search={server-name}`
2. **Get by UUID**: `GET /v0/servers/{uuid}`

This PR updates the documentation to show the correct verification
method using the search endpoint.

Fixes #410
