Change permissions from read to write for contents

OpenDroneMap#263 added granular permissions to grant `id-token: write` (which isn't granted by default). When doing this, I also added `contents: read` because granular permissions overwrite repo-level permissions, and not having it prevented the workflow from cloning its own repo.

However, the `svenstaro/upload-release-action` action requires `contents: write`, which the pipeline no longer had. Change `contents` to `write` (which implies `read`) to fix that.
