disable cache control on check for update

[farfromrefug]

When using electron http request, you don't set a cache control.
This created an issue for me while getting the latest.json. It was always reading the cache even the file actually changed on my server.
To fix that i actually just added:

        options.headers = options.headers || {};
        options.headers['Cache-Control'] = 'no-cache';

here (though i am not using the very last version)

Do you use electron-updater 1.3.1+?

We do

electron-builder/packages/electron-builder-http/src/httpExecutor.ts

Line 286 in 02a96f4

headers["Cache-Control"] = "no-cache"

Was fixed this week.
