Hi @manuzhang , I saw that the Dependabot PR was closed to open up this opportunity for newcomers. I would love to take this as my first contribution to Iceberg!

Could you please assign it to me? I can verify the build and submit the PR shortly.

@HITzengyz We avoid assigning issues. Feel free to open a PR.

Thanks @manuzhang for the guidance!

I've opened #15143. I have verified the build locally with the new wrapper version and everything looks good. ：）
