chore: fix CI code coverage publishing (#78)
chore: fix CI code coverage publishing (#78)

The code coverage publishing in package.json works fine on non-ubuntu systems.
However, in Ubuntu `/bin/sh` is symlinked to `/bin/dash` which doesn't support
everything supported by `/bin/bash` - specifically `-o pipefail`.

This commit changes the code coverage script to explicitly use `bash` instead.
