docs(examples): add example scripts for orcid-works-cli

[hyperfinitism]

Adds two example scripts (Bash & PowerShell) that demonstrate the delta‑fetch feature of orcid-works‑cli.

What's new

examples/orcid-works/test.sh

Bash script that

1. fetches ORCID Works (Detail) and saves them as output.json;
2. mutates the file with filter.jq;
3. re-runs the CLI with and without the --force-fetch flag to compare diff‑fetch behaviour.

This script is based on the How to try it section in PR #3.

examples/orcid-works/test.ps1

Functionally identical PowerShell version of the script above.

examples/orcid-works/filter.jq

Re‑usable jq filter used to tweak the JSON between fetch runs.
