fix: version prefix 'v' is missing for docker-compose v2

* System naming for docker-compose >= 2.0 fixed

As you might notice they started naming releases using not capitalized system name starting from `docker-compose` v2.0.0 ([ref](https://github.com/docker/compose/releases/tag/v2.0.0)).
This commit adds version check and fixes system name (returned by `uname -s`).

* Update src/install.ts

Naming for later versions updated

* Parsing instead of lexicographical order applied

* Update src/install.ts

* Version tag for releases >= 2.0.0 fixed

* Indentation restored

* js files compiled

* auto-appending 'v' added
