Docs: Publish Upgrade Guide for V3

[leandrodamascena]

What were you searching in the docs?

Similar to what we did when we released V2, we need to write a clear and concise upgrade guide to help customers migrate from V2 to V3.

Is this related to an existing documentation section?

https://docs.powertools.aws.dev/lambda/python/latest/upgrade/

How can we improve?

Write the upgrade guide.

Got a suggestion in mind?
