Automatically copy env file from the example file when non-existing

[123mpozzi]

Description

Right now, when the .env file does not exist, yarn boostrap script will exit prompting you to copy it from .env.example and compile it.
We can actually remove one step by automatically copying the example file, and only prompt the user to compile it.

Checklist

• 🗒 CHANGELOG entry - no need since this is a QoL change

I'm not a fan of this. If you ignore the warning you will have a non-working project.
What is the problem with bootstrap failing when you don't have the env set up?

The warning is not ignored, it is still there, but the file is created automatically.
So the non-working project is still guarded against:

BITMOVIN_PLAYER_LICENSE_KEY is not set in example/.env. Please follow the setup instructions in example/README.md.

I still don't get the benefit of these changes.
The original error message prompted you to copy the file.
We now auto-copy but it still fails and is no different functionally than before.

Why is this better than before?

It saves you the copy operation, it's not a crazy change, but I think that's already more convenient.
I don't see the value in prompting the user to copy the file when we can already do that
