examples: regenerate them when version.texi changes

Browse Source 
When we extract the examples from the documentation, %require
"@value{VERSION}" is replaced with the current version.  If we change
the git branch, without changing the documentation, the generated
examples will %require a version of Bison that differs from the actual
version.

* examples/local.mk (extracted.stamp): Depend on doc/version.texi.
