Remove Download option from the Updates Screen

[dd32]

Currently the Updates screen offers the option to either update to the new version of WordPress, or to download the ZIP.

Is downloading the zip really the action that a significant number of WordPress users are going to perform? Is it more likely to confuse a number of users?
By removing the extra button we can simplify the interface slightly (It'll be easier for design iterations on the screen too I expect) and use the real estate for more important things.

For those users who do use it, we should probably be offering a link to the release post (or similar) there instead.

I would venture to guess that users who want to try and update manually already know what they're doing and why they want to update that way. I think removing this removes yet another way a user can shoot themselves in the foot.

While working on Shiny Updates I noticed this bloated UI as well and I think "Update Now" and "Re-install now" should be the only options.

For those users who do use it, we should probably be offering a link to the release post (or similar) there instead.

We already show a "View version xy details" link for plugin updates, so the same could probably be done for core too.

Here's how we imagined this to look like in one of the latest mockups: ​https://github.com/obenland/shiny-updates/issues/5#issuecomment-176360299

Just created a patch and attached a screenshot. If shiny updates gets into 4.6 it will be obsolete, but I made it nonetheless.

Moving to 4.7 for consideration.

As mentioned in the bug scrub on Monday, we'll need some data to support this.

Edit: Scratch that. We do not really have any data for this.

Updates: Remove the 'Download' button on the Updates screen.

Props swissspidy.
