simple actions client / webohook helper WIP

[matej21]

Introducing a new package that makes it easier to write webhook handlers for Contember Actions. The package includes TypeScript types, validation features, and abstraction for popular cloud function providers such as Cloudflare, Azure, AWS Lambda, Google Cloud Functions, and Vercel Functions.

random dev notes:

• cloudflare works well
• aws works well, handler needs to be changed to index.default
• azure - esm export does not work
• google cloud - cjs or esm with "module" or mjs extension
