Improving Version Display in npx @astrojs/upgrade Command

[outslept]

Body

Summary

Currently, npx @astrojs/upgrade command shows only the target version like @astrojs/tailwind will be updated to v5.1.3. This RFC proposes to enhance the output by showing both current and target versions for better visibility

Background & Motivation

The current output format lacks clarity in showing version changes. Adding a simple "from -> to" format would improve visibility and DX when updating Astro packages.

Goals

• Make the upgrade process "more transparent"
• Simplify version change tracking
• Improve DX during updates

Example

Current output:

@astrojs/tailwind will be updated to v5.1.3

Proposed output (or mb some variation of this):

@astrojs/tailwind: v.x -> v5.1.3

Or we can just remain the same style and do it like this:

@astrojs/tailwind will be updated: v.x -> v5.1.3

This is a good idea I think. I think we’d be happy to receive a PR for this if you wanted to tackle it — no need for a small thing like this to go through the RFC process.
