refactor(setup-dev-env.sh): make the target playbook configurable

[kenji-miyake]

Description

Considering that users fork this repository and customize the configurations depending on their system, it is useful to change the meaning of the argument.

With this change, users can do like the following:

# Add some roles for their system
vim ~/autoware.customized/ansible/roles
vim ~/autoware.customized/ansible/playbooks/customized_playbook.yaml

# Replace the base name
sed -e "s/autoware.dev_env/autoware_customized.dev_env/g" setup-dev-env.sh

# Call the playbook
./setup-dev-env.sh customized_playbook
