docs: add pullRequestTestSecrets settings to v1 API spec [TREX-2727]

[nick-watson]

What does this change do?

• Adds pullRequestTestSecretsEnabled and pullRequestTestSecretsSeverity to the v1 API spec
  • Documented on the org settings schema, alongside the existing pullRequestTestCode* properties
  • Included in the request and response examples for GET/PUT /org/{orgId}/settings

Why do we need this change?

• https://snyksec.atlassian.net/browse/TREX-2727
• The v1 spec in this repo is the source of truth for the v1 API reference, so these fields need adding here to surface on docs.snyk.io.

Notes for the reviewer

• Schema properties only — no new endpoints, so snyk-api/reference/, SUMMARY.md and changelog.md are unchanged. Verified by running the API docs generator locally.

Low Risk
OpenAPI documentation only; no runtime or endpoint behavior changes.

Overview
Documents Snyk Secrets pull-request test org settings in the v1 OpenAPI spec (Integrationsettings), parallel to the existing Snyk Code fields.

Adds pullRequestTestSecretsEnabled (boolean) and pullRequestTestSecretsSeverity (low / medium / high) on the org settings schema and in the GET/PUT /org/{orgId}/settings JSON examples so they appear on the public API reference.
