Configure environment variable settings globally

Configure environment variable settings globally.

User story:
As a developer, I want to set environment variables globally, so that they don't lose their values ​​when changing terminal sessions.

DoD:

• Variables are retrieved from the .env file (or other required file containing environment variables)
• Environment variables should be available across different terminal sessions.

Technical details:

• The problem is that if you set environment variables with export variable_name=variable_value in one terminal, the variables will not be available when working in another.
• A possible solution can be considered.
