angular: fix readme for dev envs (#260)
I accidentally edited the wrong `README`, which was the inner one
from the app generated by Angular CLI rather than the project
one about Compose.

Restored the old one and moved the dev envs info to the root/Compose
README.

Compose sample

Angular service

Project structure:

.
├── angular
│   ├── Dockerfile
│   ├── ...
│   ├── ...
│   ....
└── compose.yaml

compose.yaml

services:
  web:
    build: angular
    ports:
    - 4200:4200
    ...

The compose file defines an application with one service angular. The image for the service is built with the Dockerfile inside the angular directory (build parameter).

When deploying the application, docker compose maps the container port 4200 to the same port on the host as specified in the file. Make sure port 4200 is not being used by another container, otherwise the port should be changed.

Deploy with docker compose

$ docker compose up -d

Expected result

Listing containers must show a container running and the port mapping as below:

$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES

After the application starts, navigate to http://localhost:4200 in your web browser.

Stop and remove the container

$ docker compose down

Use with Docker Development Environments

You can use this sample with the Dev Environments feature of Docker Desktop.
