Remove the self-import of isDev.

The self-import conflicts with the local export function isDev declaration and prevents TypeScript compilation. Remove the import; tableMemo can call the local function directly.

In `@packages/table-core/src/utils.ts` at line 2, Remove the self-import of isDev
from the module and keep tableMemo calling the local exported isDev function
directly.
