Use a capital B to represent bytes in download progress
Change the download progress to use a capital B to represent bytes instead of a lowercase b (which normally represents bits).
Old behavior:
```
Fetching @go_sdk; fetching 69s
Fetching ...; 19,298,881b 69s
```
New behavior:
```
Fetching @go_sdk; fetching 69s
Fetching ...; 19,298,881B 69s
```
Closes #10743.
