Make dependency version policy more strict.

[LoicPoullain]

Issue

1. We had issues in the past with dependencies which broke the application on a minor release (which in theory should not happen).

2. Since v4.17.0, Express exposes the method text of the body-parser. We do not need to have it in the dependencies anymore.

Solution and steps

• Dependencies (except peer ones) specified in the package.json should point to minor versions. Each release of Foal TS should upgrade these versions.
• Use recent versions (for direct dependencies). Especially update mongodb minor version (cf MongoDB connection timeout - Remote server with username/password #556).
• Remove body-parser dependency.

Checklist

• Add/update/check docs (code comments and docs/ folder).
• Add/update/check tests.
• Update/check the cli generators.
