Add vPrefixedTagName for auto update

[alexbrazier]

• Cersion: 16.4.2

• Target: macOS

The publish option vPrefixedTagName should be added for auto update as the the latest-mac.json file and the auto update request to get the latest version will always assume that the url is v1.0.0 instead of just 1.0.0, causing errors if you don't tag releases starting with a v

We write publish config as is, so, vPrefixedTagName is already available for GitHubProvider.

But! Due to Squirrel.Mac limitation we have to build url in-advance — build-time. So computeDownloadUrl should be fixed.

Done — will be released in 10 minutes.

Awesome, thanks for the quick fix.
There also appears to be an issue with GitHubProvider.ts in a couple of places where the url is hardcoded with a v e.g. https://github.com${basePath}/download/v${versionInfo.version}/${name}, is it possible to use the vPrefixedTagName tag name for this as well?

Yes, you are right, it is a part of fix.
