Fix bun.lock formatting of bin

[dylan-conway]

What does this PR do?

bin was missing a newline, causing weird formatting. Also adds a space between value and key for cpu and os, which was removed accidentally (only in canary).

How did you verify your code works?

Added a test that snapshots most things the lockfile formatter will print.
