internal/godebugs: fix changed version for winsymlink and winreadlinkvolume to 1.23
https://go.dev/doc/godebug#go-123 documents changes to winsymlink and
winreadlinkvolume in Go 1.23.
This fixes the registered "changed" minor version to Go 1.23,
so that defaults when building a Go 1.22 module are correct.
Fixes #72935
