fix: services.core.ports contains an invalid type

[strophy]

Removes quotes from generated .env file, since these are not handled by docker-compose.

Issue being fixed or feature implemented

Trying to start a node with mn config:envs -o .env && docker-compose up fails with various errors as follows:

services.core.ports contains an invalid type, it should be a number, or an object
ERROR: .FileNotFoundError: [Errno 2] No such file or directory: './"docker-compose.yml"'

According to the env file spec:

• There is no special handling of quotation marks. This means that they are part of the VAL.

What was done?

Remove quotes from generated output.

How Has This Been Tested?

mn config:envs -o .env && docker-compose up
--> no errors, services start as expected
