feat: On scoop update show bucket names to help debbuging on git conflicts

[raisercostin]

Having the name help in debugging what buckets have git conflicts.

Description

Show what buckets are updated.

Motivation and Context

When updating via scoop update some buckets have conflicts.
Is hard to even see which ones since the updating buckets is not shown:

λ scoop update
Updating Scoop...
Updating Buckets...
error: cannot pull with rebase: You have unstaged changes.
error: Please commit or stash them.
Scoop was updated successfully!

After this fix you get

λ scoop update
Updating Scoop...
Updating Buckets...
error: cannot pull with rebase: You have unstaged changes.
error: Please commit or stash them.
WARNING: Git failed in D:\home\raiser-apps\buckets\jumpchat
Scoop was updated successfully!

How Has This Been Tested?

Just run scoop update and the list of buckets should be shown.
