Refactor project package

[EvandroLG]

A small refactor in the project package, incorporating the following adjustments:

• Introduces a new class dedicated to handling folder creation and deletion
• Renames the project file to dev_container_cli
• Implements logic to delete the project folder in case of errors.

I added all the best from this PR in #7. So I guess we can close it?
