`stack upgrade` tries to download bindist with missing or unknown extension

### Steps to reproduce

Note: this example is for macOS, but similar steps can be used by adjusting the filenames for other platforms.

1. Upload a file named `stack-2.1.3-osx-x86_64` or `stack-2.1.3-osx-x86_64.bin` to the [Github release of Stack](https://github.com/commercialhaskell/stack/releases/latest)

2. On a machine with an older version of `stack`, run `stack upgrade`.

### Expected

`stack upgrade` should ignore `stack-2.1.3-osx-x86_64` or `stack-2.1.3-osx-x86_64.bin` since those aren't known extensions. It should only try downloading `.tar.gz` or `.zip` files, since those are the only extensions it supports.

### Actual

`stack upgrade` tries to download the `.bin` (or bare) file, even though a `.tar.gz` file also exists, and then fails (and falls back to source upgrade) because it has an unknown archive format.

```
$ stack upgrade
Current Stack version: 2.1.1, available download version: 2.1.3
Newer version detected, downloading

Warning: Exception occured when trying to perform binary upgrade:

### Stack version

```
$ stack-2.1.1 --version
