docs: Mark APIs internal (ET-694)

[jesse-amano-hpe]

Ticket

ET-694

Description

In our audit of experiment tracking related APIs and how they're used, we found that these endpoints should be marked as internal in our docs, and will not have "run-centric" equivalents.

Test Plan

Generated Swagger docs show these endpoints as internal

GET /api/v1/experiments/{id}/file_tree
GET /api/v1/experiments/{id}/model_def
GET /api/v1/experiments/{id}/validation-history
POST /api/v1/preview-hp-search
GET /api/v1/trials/time-series
GET /api/v1/trials/{id}/logs/fields
GET /experiments/{id}/file/download (note there isn’t even a /api/v1 prefix)

Checklist

• Changes have been manually QA'd
• New features have been approved by the corresponding PM
• User-facing API changes have the "User-facing API Change" label
• Release notes have been added as a separate file under docs/release-notes/
  See Release Note for details.
• Licenses have been included for new code which was copied and/or modified from any external code
