load.sh and load.ps1 nits

[GrahamHannington]

load.sh

Usage example comments reflect the old positional command-line parameters, not the new named parameters:

# Usage examples:
# env KIBANA_INDEX='.kibana_env1' ./load.sh
# ./load.sh http://test.com:9200
# ./load.sh http://test.com:9200 test

load.sh and load.ps1

Usage text mentions "dashboards, visualizations, and index patterns", but not searches.

Typo in the usage text for the -url option: "Elasticseacrh" (sic).

I know, I'm a pedant :stuck_out_tongue:.

@GrahamHannington As always, thanks for mentioning this. Good docs (and especially correct docs) are as important as good code.
