fix (tests) : update userstory path to specs/dashboard-samples (#23514) (#23515)

The test script was previously checking for user stories under `specs/devfiles`,
which no longer exists or contains relevant test specs. This commit updates the
`checkUserstoryName` function to look in `specs/dashboard-samples`, where the
current user story specs (e.g., `*.spec.ts`) are now located.

This resolves issues where valid USERSTORY values were incorrectly reported
as missing.
