Remove ROR v1 support from indexing and dump workflows

[jrhoads]

Purpose

The purpose of this PR is to deprecate and remove support for ROR Schema version 1 (v1) from the manual indexing and index dump CI/CD workflows. This ensures the workflows primarily target the current v2 schema.

Approach

The changes involve updating GitHub Action workflow files to remove logic branches and input options related to v1.

Key Modifications

• dev_index_dump.yml:
  • Removed v1 from the schema version choice list.
  • Simplified the script execution to strictly use the INDEX_DUMP_DEV_API_URL_V2 secret, removing the conditional check for schema versions.
• dev_manual_index.yml:
  • Removed v1 from the schema version choice list.
  • Removed the validation step logic specific to v1 (which used the master ror_schema.json).
  • Removed the indexing step logic specific to v1 (which used the INDEX_DEV_API_URL_V1 secret).

Important Technical Details

• The workflows now default to using the V2 API endpoints and secrets.
• Validation for schema versioning in dev_manual_index.yml now focuses exclusively on the v2_1 schema specification.

Types of changes

• Breaking change (fix or feature that would cause existing functionality to change)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
