fix(ngts): refresh NGTS spec (path cleanup + fingerprint field clarification)

[rajitshah-ca]

What

Refreshes the NGTS (Venafi TLS Protect Cloud) OpenAPI spec on pan.dev from the latest ua-repo pan.dev pipeline runs:

• pipeline 2838826459
• pipeline 2848060423

Changes

• Certificate endpoint paths: dropped the /outagedetection prefix (e.g. /outagedetection/v1/certificates -> /v1/certificates). This matches the same path change already deployed to developer.venafi.com by the same pipeline run's Dev Central job (Deploy API Production), so this brings pan.dev in line with what's already live on the primary docs.
• "Built-in Accounts" tag casing: corrected from Built-In Accounts to Built-in Accounts, matching ua-repo's source of truth (siteconf-pandev.yaml), which was corrected there shortly after the capitalized version was originally published to this repo and never republished.
• existingCertificateFingerprint field description clarified: CertificateRequestRequest.existingCertificateFingerprint now specifies it's a SHA-1 fingerprint (was previously just "Fingerprint of an existing inventory certificate...").
• New containerFormat query param on GET /v1/certificates/{id}/contents, and a new POST /v1/machines/workflows endpoint (machines_initiateTestConnectionWorkflow), carried over from the regenerated spec.

No Docusaurus config, sidebar, or generated page changes needed — generated files aren't committed (built at deploy time), consistent with #1311.

Motivation and Context

EPIC: VC-50859

How Has This Been Tested

• Verified path/naming changes against ua-repo source (siteconf-pandev.yaml, operationsDoc/) and confirmed the path change is already live on developer.venafi.com via the same pipeline run.
• Diffed schema-level field descriptions between pipeline runs to confirm the existingCertificateFingerprint wording change and rule out unrelated component $ref renumbering noise.
• Validated the spec is well-formed JSON.
