PE: Update examples for classifier nodes endpoint

[bastelfreak]

Describe the Bug

https://www.puppet.com/docs/pe/2023.8/nodes_endpoint.html lists some URL examples. The text says

When Forming node classifier API requests to this endpoint, the request is a basic GET call with authentication

but also:

GET https://localhost:4433/classifier-api/v1/nodes?limit=25&offset=25

Which doesn't work out of the box.

Expected Behavior

A working copy and paste example would be awesome:

cert="$(puppet config print hostcert)"; \
cacert="$(puppet config print localcacert)"; \
key="$(puppet config print hostprivkey)"; \
uri="https://$(puppet config print server):4433/classifier-api/v1/nodes?limit=25&offset=25"; \
curl --cert "$cert" --cacert "$cacert" --key "$key" "$uri"

Steps to Reproduce

Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'

Environment

• Version [e.g. 1.27.0]
• Platform [e.g. Ubuntu 18.04]
