Docs: Idempotency docs say only Middy v3.x is supported

[buggy]

What were you searching in the docs?

I was reading the whole Powertools for AWS Lambda (Typescript) docs.

Is this related to an existing documentation section?

https://docs.powertools.aws.dev/lambda/typescript/latest/utilities/idempotency/#makehandleridempotent-middy-middleware

How can we improve?

Immediately below the heading "MakeHandlerIdempotent Middy middleware" there is a "A note about Middy" which says that only v3.x is support. Other parts of the documentation say v4.x

Got a suggestion in mind?

Change v3.x to v4.x

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.

Hey @buggy , thanks for dropping the issue that we have missed during the upgrade to v2. Dropping the fix asap.

Found additional inconsistencies:

• powertools-lambda-typescript/docs/index.md

  Line 267 in bf0aa4b

  * **Middy** middleware. It is the best choice if your existing code base relies on the [Middy 3.x](https://middy.js.org/docs/) middleware engine. Powertools for AWS Lambda (TypeScript) offers compatible Middy middleware to make this integration seamless.

• powertools-lambda-typescript/docs/core/metrics.md

  Line 203 in bf0aa4b

  Currently we support only Middy `v3.x` that you can install it by running `npm i @middy/core@~3`.
