feat(action): always print x-deno-ray for debuggability

[magurotuna]

This commit makes x-deno-ray values always printed in GitHub Actions as soon as we get a response from the backend API server.

The primary motivation behind it is that it's hard to debug issues with streaming APIs - in particular, gitHubActionsDeploy:

deployctl/src/utils/api.ts

Lines 410 to 424 in acb2ba3

	gitHubActionsDeploy(
	projectId: string,
	request: GitHubActionsDeploymentRequest,
	files: Uint8Array[],
	): Promise<AsyncGenerator<DeploymentProgress>> {
	const form = new FormData();
	form.append("request", JSON.stringify(request));
	for (const bytes of files) {
	form.append("file", new Blob([bytes]));
	}
	return this.#requestJsonStream(
	`/projects/${projectId}/deployment_github_actions`,
	{ method: "POST", body: form },
	);
	}

This API returns 200 OK and then starts streaming the progress. But currently x-deno-ray is not printed when the status code is 200. Problems that happen during streaming, e.g. very slow file uploads, could be made easier to debug by making x-deno-ray available in this case too.
