Merge twenty-cli into twenty-sdk (#16150)

- Moves twenty-cli content into twenty-sdk
- add a new twenty-sdk:0.1.0 version
- this new twenty-sdk exports a cli command called 'twenty' (like
twenty-cli before)
- deprecates twenty-cli
- simplify app init command base-project
- use `twenty-sdk:0.1.0` in base project
- move the "twenty-sdk/application" barrel to "twenty-sdk"
- add `create-twenty-app` package
