Use new direct download URL for links to download Firefox

As a result of an experiment run a few months ago, the Bedrock team has implemented a download page that will start a download automatically, as opposed to requiring users to click a download button on www.mozilla.org. In order to use this new page, one links to the thanks page and adds the query param of s=direct to the download URL, as documented here.

This issue is about updating the destination of our “Get Firefox” buttons to point to this new direct page.

For QA: Downloading Firefox from either the button on an add-on detail page, or from the banner that appears on all other pages, should result in an immediate download of Firefox from https://www.mozilla.org/firefox/download/thanks/. The URL should include the s=direct parameter. If downloaded on a Windows device, the correct attribution data should be recorded and end up in telemetry.

@ioanarusiczki I have made the updates and the blog should now be using the correct destination on its buttons.

Thanks for calling this out!

Thanks @ioanarusiczki, that all sounds good, except for…

1. Are the blog addon cards expected to behave the same way? Right now the blog on stage redirects to the other page mozilla.org/en-US/firefox/new where the manual download is required but probably changes are going to be visible after the push ?

I think I need to do a new release of addons-frontend-blog-utils in order to pick up the change in the download button. I will do that and report back.
