Skip publishing lambda layers for pre-releases

[andreiborza]

Description

We published an alpha release of the sentry-javascript SDKs earlier today and despite it being an alpha-release, the Lambda layer was published.

We brought this up previously in this issue but thought this function prevents publishing the layer:

craft/src/targets/awsLambdaLayer.ts

Lines 196 to 209 in 532b8d1

	private isPushableToRegistry(version: string): boolean {
	if (isDryRun()) {
	this.logger.info('[dry-run] Not pushing the branch.');
	return false;
	}
	if (isPreviewRelease(version) && !this.awsLambdaConfig.linkPrereleases) {
	// preview release
	this.logger.info(
	"Preview release detected, not updating the layer's data."
	);
	return false;
	}
	return true;
	}

Upon further reflection, the function is just used to prevent publishing to our release-registry but it does not prevent publishing the layer to AWS.

Expected Result

Pre-releases not to publish our production AWS Lambda layers on AWS.

Actual Result

Pre-release published a new version of our AWS Lambda layer on AWS.
