Update metadata.ts files when releasing a new version

[seratch]

Currently, the following files are not updated while the release job successfully adds correct version metadata to the deployed npm packages.

	modified:   packages/agents-core/src/metadata.ts
	modified:   packages/agents-extensions/src/metadata.ts
	modified:   packages/agents-openai/src/metadata.ts
	modified:   packages/agents-realtime/src/metadata.ts
	modified:   packages/agents/src/metadata.ts

We want to keep these files in git version control so that the release CI job should update them to be up-to-date.
