Minor DevContainer adjustments

* Add gnupg2 to be able to sign commits
* Make sure /var/www/html always belongs to www-data
* Add Git-History plugin
* Introduce dedicated entrypoint script
* Store Postgres database data in volume to be persistent
* Cleaner check if NC is already installed in setup.sh
* Add composer to DevContainer

+# Nextcloud DevContainer
+
+## Usage
+
+Make sure you have the [VSCode DevContainer](https://code.visualstudio.com/docs/devcontainers/containers) extensions installed. If you open the project, VSCode will ask you if you want to open it inside of the DevContainer. If that's not the case, use <kbd>F1</kbd>&rarr;*Dev Containers: Open Folder in Container*.
+
+Alternatively open the project directly in [GitHub Codespaces](https://github.com/features/codespaces).
+
+That's already it. Everything else will be configured automatically by the Containers startup routine.
+
+## Credentials
+
+On first start the Container installs and configures Nextcloud with the following credentials:
+
+**Nextcloud Admin Login**
+
+Username: `admin` <br>
+Password: `admin`
+
+**Postgres credentials**
+
+Username: `postgres` <br>
+Password: `postgres` <br>
+Database: `postgres`
+
+## Services
+
+The following services will be started:
+
+| Service | Local port | Description |
+|---------|------------|-------------|
+| Nextcloud (served via Apache) | `80` | The main application |
+| Mailhog | `8025` | SMTP email delivery for testing |
+| Adminer | `8080` | Database viewer. Use credentials from above and connect to `localhost:5432` to get access to the NC database | 
+
