Update OpenAPI spec: document include_deleted on detail/history endpoints

[tadasant]

Context

PR #893 added include_deleted query parameter support to multiple endpoints, but the OpenAPI spec (docs/reference/api/openapi.yaml) only documents it on the list endpoint.

Ref: #893 (review)

What needs updating

The include_deleted query parameter (boolean, default false) should be added to the OpenAPI spec for:

• GET /v0.1/servers/{serverName}/versions/{version} — version detail endpoint
• GET /v0.1/servers/{serverName}/versions — version history endpoint

It's already documented on GET /v0.1/servers (the list endpoint).

Notes

• The code already supports include_deleted on all three endpoints — this is purely a spec documentation gap
• The official-registry-api.md and CHANGELOG.md were updated in Publisher-managed "deleted" support #893; only the OpenAPI spec was missed
