AWS SDK v3 Support (v2 deprecation)

[throrin19]

Problem Statement

Actually, @sentry/serverless package use the aws-sdk v2. It results on this warnings when testing in local with serverless-offline :

(node:49034) NOTE: We are formalizing our plans to enter AWS SDK for JavaScript (v2) into maintenance mode in 2023.
Please migrate your code to use AWS SDK for JavaScript (v3).

With lambdas using the node18 runtime, the sdk available is the v3, not the v2. To be able to use the sdk in v2, it must be included in the package, which makes the size of each lambdas quite substantial.

Solution Brainstorm

Use the sdk v3. But, with that, we have the problem of compatibility between aws node runtime < node18 using the sdk v2 and aws node runtime >= node18 using the sdk v3
