chore(studio): Update Studio URL to new domain (#10538)

* chore(studio): Update Studio URL to new domain

The https://studio.dvc.ai is deprecated, and we switched to the new domain https://studio.datachain.ai.

The domain change is backwards compatible. The **older versions** of the `dvc` will still work. 🎉
