Release notes clone mismatch in 1.10.0-SNAPSHOT

[Gerd Aschemann]

As far as I can see, almost all of the src/main/asciidoc/releasenotes/1.9 and 1.10 files were cloned/changed in the wrong way: The 1.9 files contain the version number for 1.10 and vice versa. Looks like an error a script which was used to clone these files?

```diff

diff -bc src/main/asciidoc/releasenotes/1.{9,10}.0.adoc
