Pull request overview

Adds dsconfig-based configuration schema support for the Amazon Timestream datasource so downstream tools (including agents) can introspect required configuration fields via a uniform schema and generated artifacts.

Changes:

• Added pkg/schema/dsconfig.json as the dsconfig single source of truth for datasource configuration fields and groups.
• Added generated schema artifacts (schema.gen.json, settings.gen.json, settings.examples.gen.json) and a conformance test (dsconfig_test.go) to validate drift.
• Updated Go dependencies (including grafana-plugin-sdk-go) to support dsconfig/schema tooling.
