chore(maintenance): bump dependencies + apply peerDependencies

[dreamorosi]

Description of your changes

This maintenance PR introduces the following changes:

• bump all project dependencies up to the latest version that still supports Node.js 14
• specify peerDependencies and peerDependenciesMeta fields in the package.json of the utility that expect the customer to install additional modules
• manually bump version in packages/commons/src/version.ts to 1.12.2 for upcoming release
• remove both Idempotency & Batch Processing from the beta channel so that at the next release they'll be GA
• fix tsconfig.json files in examples to more closely align with rest of the repo - the examples will still maintain a full config file despite all the rest of the project sharing the same, this is done for educational purposes as customers might look at the example folder in isolation

Successful e2e test run: https://github.com/aws-powertools/powertools-lambda-typescript/actions/runs/6197147946/job/16825788109

During the first run one test failed due to Tracer tests being fickle at times.
