[SPARK-50711][PS][DOCS] Upgrade the minimum version of Pandas in PS to 2.2.0

### What changes were proposed in this pull request?
Upgrade the minimum version of Pandas in PS to 2.2.0

But the version used in `require_minimum_pandas_version` is still 2.0.0, because currently this function is used in both PS and non-PS modules.

### Why are the changes needed?
Actually, PS with Pandas < 2.2.0 has already been broken in master branch

### Does this PR introduce _any_ user-facing change?
No, doc-only

### How was this patch tested?
CI

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

Closes apache#49344 from zhengruifeng/ps_pd_mini.
