Simplify 'check' task in turbo.json

Remove the unnecessary dependsOn configuration for the "check" task in
turbo.json. The task had a dependency on "package" which is not
required, so this change cleans up the task definition by making it an
empty object, aligning it with other simple tasks and avoiding
unintended task ordering or execution.

These changes are safe for CI- the workflow builds all necessary
packages and generates type definitions before running `pnpm check`, so
removing the package dependency from the check task won't break the
build.
