Update matcher regex in middleware.ts / proxy.ts

Description

The current matcher

content-sdk/packages/create-content-sdk-app/src/templates/nextjs/src/proxy.ts

Line 76 in af0b249

* 7. all root files inside /public

/*
 * Match all paths except for:
 * 1. API route handlers
 * 2. /_next (Next.js internals)
 * 3. /sitecore/api (Sitecore API routes)
 * 4. /- (Sitecore media)
 * 5. /healthz (Health check)
 * 7. all root files inside /public
 */
matcher: [
  '/',
  '/((?!api/|sitemap|robots|_next/|healthz|sitecore/api/|-/|favicon.ico|sc_logo.svg).*)',
],

It hasn't been updated since JSS days, and since then we don't get /sitecore/api (Sitecore API routes) or /- (Sitecore media) being proxied. Also the 7. comment looks a bit misleading.

I also notice that most next.js examples e.g https://github.com/vercel/turborepo/blob/main/apps/docs/proxy.ts#L71C6-L71C51 tend to have _next/static|_next/image.
