Adds a Set your credentials step to the README. It covers exporting BROWSERSTACK_USERNAME / BROWSERSTACK_ACCESS_KEY in the shell (macOS/Linux and PowerShell) and never committing them. The CLI reads both from the environment.

Stacked on #3, which brings the sample and this README to main. Merge #3 first, then retarget this PR to main (GitHub does that automatically only if #3's branch is deleted on merge).
Asked for in BrowserStack Security's retest of LTS-5452: the sample READMEs had no step for setting credentials.

Systems and components

• observed — README.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in README.md: The setup bullet now links to the credentials section instead of directly naming the environment variables and linking to Account Settings. The Node.js/npm requirement, dependency installation, and configuration steps remain.
• observed — Modified behavior in README.md: Added credential instructions with macOS/Linux and PowerShell examples; both prompt for the access key without echoing it. The section notes that credentials apply only to the current terminal session and advises checking both variables after an authentication error. It warns against committing credentials or putting the access key in pushed files and advises regenerating an exposed key.
