Proposal: Use the conventional commit specification for kci-dev

[CamilaAlvarez]

https://www.conventionalcommits.org/en/v1.0.0/#specification

These would allow us to automatically generate changelogs that are clearer to the users.

Since the project is still fresh I think we could still adapt this convention with no major issues.

Thanks for the proposal,
I think this can be added as a format suggestion in the contributing document
