docs: Regenerate connector docs with fixed YAML quoting

Regenerated all connector documentation using fixed YAML serialization
that properly quotes strings with special characters.

Key fix:
- Strings with newlines/whitespace now properly quoted (e.g., "\n\n", "\n")
- Fixes misleading block scalar format (|+) that appeared empty
- Also fixes other string values like "POST", "all", etc.

Changes:
- Updated to connector spec version 4.78.0
- Added OTLP gRPC/HTTP input/output connectors
- Fixed YAML string quoting in both example files and field documentation
- Updated whats-new.adoc with version 4.78.0 changes

Uses @redpanda-data/docs-extensions-and-macros with QUOTE_DOUBLE fix
applied to toYaml.js, renderLeafField.js, and renderConnectFields.js.

This completely addresses the CodeRabbit issue from PR #362 where
separators appeared as empty block scalars in the field documentation.
