docs: Update pyiceberg CLI help docs

[el10savio]

Hi folks, big fan of Iceberg! I noticed a tiny change in the cli docs. Correcting it here.

Rationale for this change

Fix docs.

Are these changes tested?

No tests against docs.

Are there any user-facing changes?

Should now reflect in https://py.iceberg.apache.org/cli/#python-cli

This was actually a joke from my end, xor referring to exclusive-or :)

LGTM! The CLI is super cool! It gives you a easy way to query a catalog and view table data.
