test: Update integration test for go1.23

- Add `testContext(*testing.T) context.Context` in `./test` package, with version-specific implementations matching `package unstructured`
- Add `randText() string` in `./test` package. Version-specific implmentation for go1.24 and later delegates to `crypto/rand.Text`, while the implementation for go1.23 simply copies the body of `crypto/rand.Text` into a local implementation.
