Improve output formatting to look more consistent with forc

[mitchmindtree]

FuelLabs/sway#4187 improves the formatting of forc's output, clearly distinguishing between the action (verb, bolded green) and subject (noun, white). We should attempt to follow the convention for actions like "Fetching", "Verifying", "Deriving", etc, including aligning actions to the 10th column.
