x/website: go1.20 docs refer to strings.Clone as new

[benpbrown]

What did you do?

Visited https://go.dev/doc/go1.20

What did you expect to see?

No reference to strings.Clone as being new. I believe it was introduced in Go 1.18 for strings (https://go.dev/doc/go1.18) (but in 1.20 for bytes 🙂 )

What did you see instead?

The following reference to a new function: The new [Clone](https://go.dev/pkg/strings/#Clone) function allocates a copy of a string.

Ah, that's probably a copy-paste error, looking at the rest of the content of each section.

I'll send out a CL.
