Feature/add mg parser

[XanderVertegaal]

This PR adds the MG Parser to ParsePort's Docker compose network.

In order to test/review this, you will need to:

• Clone the https://github.com/CentreForDigitalHumanities/mg-parser-server repo and put it in the same folder as the parseport project folder. (Make sure parseport and mg-parser-server are siblings.)
• Checkout out the feature/basic-api branch in mg-parser-server.
• Run the following command in the main parseport directory to build a network with dev containers:

docker compose --profile dev up --build -d

(The Angular container pp-ng may take a while - check its logs to see its progress.) After everything is booted up, go to http://localhost:5000,visit the parser at Minimalist Parser > Parse sentence and wait a few seconds.

If you see the following:

It means the MG Parser server has responded with a {"status": "ok"}, meaning that it is ready to receive requests!

Enter an English sentence, hit 'Submit' and check the pp-mg-parser container logs. If you see a message similar to the one below, your input was successfully parsed.
