Version of the current codebase

* Version is based on a root project file named `version.edn`.
Strengths:
* One source of truth for version.
* Change of version in a PR is more straightforward to notice
* Flexibility (We don't decide on versioning strategy, we just have file that is point of reference to what version you are on.)
Constraints:
 * Keeping up with updates for version files (although with automated tooling we have, it is not that big of a deal currently)

Previous design:
* major version has to be changed in the major-version in `build_config.edn` (many sources of truth and build_config shouldn't be a place that is used as variable that change often)
* counting commits from a branch to base a minor version on it (Many edgecases where commits don't match the version, initial commits, PRs having more than one commit...)
