Update Server returns the URL of blockmap, blocking auto update

[amatzen]

Hi,

When using the hosted update.electronjs.org server, I get the blockmap URL in the url property of the response object, instead of the ZIP-file for the macOS distribution. This blocks the auto update function for us.

However, for a forked repo used for testing, I get the proper zip file in the url property.

https://update.electronjs.org/servicepos/printdesk/darwin-x64/v1.62.5
https://update.electronjs.org/amatzen/printdesk/darwin-x64/v1.62.5

I suspect the RegEx here to falsely turn positive on Printdesk-1.62.6-mac.zip.blockmap:

update.electronjs.org/index.js

Lines 268 to 270 in f0d89fe

	if (/.*(mac|darwin|osx).*\.zip/i.test(fileName) && !/arm64/.test(fileName)) {
	return PLATFORM_ARCH.DARWIN_X64
	}
