…rk box plot

### What changes were proposed in this pull request?
Add parameter "precision" to pandas on Spark box plot.

### Why are the changes needed?
Previously, the box method used **kwds, allowing precision to be passed implicitly. Now, adding precision directly to the signature ensures clarity and explicit control, improving usability.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
Existing tests.

### Was this patch authored or co-authored using generative AI tooling?
No.

Closes #48445 from xinrong-meng/ps_box.
