refactor: Only pass commit sha for installing launcher CI build (#313)

* refactor: Only pass commit sha
for installing launcher CI build

This allows for easier usage later when installing a launcher build
based on commit sha only, e.g. for installing newest build of a branch.

* docs: Update comments to match current code
