Install starter-scripts via Python #121
Description
Background
The clients of script-languages-container-toll currently need to execute the bash scripts (under folder installer) to install the starter scripts. This has the big disadvantage that the version of the script-languages-container-tool needs to be defined there, too.
It would be better to have a dependency only to the Python package; this allows automatic version conflict detection via Poetry.
For that, the Python package should support installation of the starter-scripts.
Acceptance
There should be a new CLI command install_starter_scripts which provides same functionality as the installer scripts.
