[Bug]: Discrepancy between CLI and Documentation

### What happened?

The documentation says that if we use the command `dab init` and specify a config file that already exists, this config file will be overwritten with the new changes. However, currently the CLI command fails and shows a message that states that the user should delete the config file manually before using the command with that specific config file name.
