chore: add build workflow

[vr4b4c]

Tasks:

• checkout fetch depth
• add build workflow

Aim

Add build workflow which for now just checks if commits which belong to the PR comply with conventional commit format.

Checkout fetch depth

By default the checkout action fetch depth is 1, meaning only the latest commit. To inspect if PR commit messages comply with conventional commit format, build job has to have access to the whole Git history. PR introduces optional checkout_fetch_depth input which is passed to the checkout action.

Solution

• add .commitlintrc config
• add checkout_fetch_depth
• containerise the app for running CI checks
• add commitlint/cli dependency
