chore: relint & update

* updated go version requirement to go1.19
* updated dependencies, excepted:
   * yaml (upgrade to v3 deferred to another PR)
   * otel (upgrade is breaking: deferred to another PR)

* ci: updated linting rules, in line with other go-openapi repos
   * exception: disabled the "nilerr" linter, which currently crashes for
     this repo
* ci:updated github actions, in line with other go-openapi repos
* doc: updated README links and badges

* major relinting of all test code
* relinting non-test code is deferred to another PR (hopefully with less changes)
* changes to non-test code are limited to:
  * addition of (temporary) nolint directives
  * gofmt/typos in comments
  * unused params

TODO in forthcoming PRs:
* [ ] upgrade to yaml/v3
* [ ] upgrade OTEL packages
* [ ] gradually remove most "nolint" directives in non-test code
* [ ] complete test refactoring: some nolint directives have been added
      to skip more complex refacoring (e.g. duplicate code)
