refactor: transform split out variables

[erisu]

Motivation and Context

This maybe a personal opinion but, I feel that split out the variables can make it:

• easier to search for the variable declaration.
• quicker to distinguish the change/add/remove of a variable in a diff when on its own line.

Description

• Use lebab to apply --transform multi-var .

Testing

• npm t

Not a big fan of these changes stylistically, but they are correct.

So if we want them, they can be merged.
