Add Type Checking and TSConfig to Bun-Create-Playwright

Now that we have installed bun, Anthropic's package manager, and scaffolded a Playwright framework and closely examined the results, we are going to explore with our Bun-Create-Playwright project ways to check if our code is correct. The first method we will be exploring is typechecking. Why Typechecking? As the Playwright.dev / Node.js Introduction mentions:"[...] Playwright does not check the types and will run tests even if there are non-critical TypeScript compilation errors. We recommend you run TypeScript compiler alongside Playwright."[...] Note that Playwright only supports the following tsconfig options: allowJs, baseUrl, paths, references and extends."[...] By default, Playwright will look up a closest tsconfig for each imported file by going up the directory structure and looking for tsconfig.json or jsconfig.json. This way, you can create a tests/tsconfig.json file that will be used only for your tests and Playwright will pick it up automatically".Before we go further down…
