fix: add default-members to workspace configuration (#226)

The 'no packages selected' error occurs because cargo-release
needs to know which packages to operate on in a workspace.

Adding default-members tells cargo (and cargo-release) which
packages to operate on when no specific package is selected.

This should finally fix the release workflow.
