fix(e2e): use specific regex for overview heading

The /intel.gpu/i regex was too broad and could match multiple headings
on the overview page, causing strict mode violations in Playwright.

Use /Intel GPU — Overview/i to match only the actual page heading,
which contains 'Intel GPU' before 'Overview'.
