test: Update examples and run integration test

The generated samples are updated with:
`./bin/generate-samples.sh ./bin/configs/manual/*.yaml`
Most example projects have their version numbers bumped. Some changes
show, that there are some other unrelated changes to the files, which
indicates that some prior commit did not update the samples accordingly.
The relevant integration test
`mvn integration-test -f samples/server/petstore/rust-axum/pom.xml`
passes.
