Subject: [PATCH] README: use a golang:1.27 image in the Docker build example
 (#8698)

The README's Compilation with Docker section builds with golang:1.25,
but go.mod requires Go 1.26.0 or higher, and .go-version (used by CI)
pins 1.27.3. Use golang:1.27 so the example satisfies the declared
minimum.

 ```
 
 The above command alone will have `coredns` binary generated.
