Fix build under typescript@7 via useTypeScriptCli

typescript@7 is the native Go port and no longer exposes the JS compiler
API that Next's built-in type checker calls into, so `next build` failed
with "TypeScript 7.0.2 does not provide the compiler API required by
Next.js". Setting experimental.useTypeScriptCli makes Next shell out to
the tsc binary instead.

Note that typescript.ignoreBuildErrors is not a workaround here -- the
build still fails after printing "Skipping validation of types".
