[BUG]: Bump `drizzle-zod` to `zod` v4

### Report hasn't been filed before.

- [x] I have verified that the bug I'm about to report hasn't been filed before.

### What version of `drizzle-orm` are you using?

0.44.3

### What version of `drizzle-kit` are you using?

0.31.4

### Other packages

drizzle-zod@0.8.2

### Describe the Bug

The Zod package version has now switched to v4 and the previous `zod/v4` is no longer used. The `drizzle-zod` package needs to be updated to accommodate these changes so that using `--legacy-peer-deps` isn't needed (which is the current workaround).
