release: try fix ci release

[dos65]

Right now, publishing snapshot artifacts fails at master branch - https://github.com/tofu-tf/tofu/actions/runs/8729099174/job/24176195801 .

I think there might be an issue related to cross compilation and project matrix.
The build prints a warning:

[warn] Issuing a cross building command, but not all sub projects have the same cross build configuration. 
This could result in subprojects cross building against Scala versions that they are not compatible with. 
Try issuing cross building command with tasks instead, since sbt will be able to ensure that cross building is only done using configured project and Scala version combinations that are configured.

Probably removing + from sbt +ci-release might fix it. Anyway + usage for ci-release isn't needed.
