Update kubectl version in deployment examples to 1.32.2

[Warashi]

What this PR does:

as title

Why we need it:

We use examples in the k8s plugin test, but there is no binary release for kubectl 1.18.0 for aarch64-darwin. So, the test fails on macOS with Apple Silicon.

There is no need to specify that old version, so I upgraded it to the latest.
