As a dev, I want to improve create_dependencies_file() so that the name of the install_if_missing parameter is more explicit

Criteria of success

• [x] The name of the parameter to check the presence of a package version is more explicit

• [x] the parameter changes the installation instruction of the remote package

Technicals

• [x] replace install_if_missing -> install_only_if_missing
• [x] Modify dependencies_file to check also {remotes}
