fix: add conventional-changelog-conventionalcommits as direct dependency (#6)

Yarn PnP's strict dependency resolution prevents accessing transitive
dependencies. The `conventionalcommits` preset is required by
`@release-it/conventional-changelog` but must be declared explicitly
for Yarn PnP to resolve it, fixing the release workflow.
