(MODULES-11099) Make merge parameter data types actually backwards compatible

This PR creates new new resources:
 * Stdlib::Http::Method for validating http methods
 * Stdlib::Http::Status This is just a copy of Stdlib::Httpstatus
 * make Stdlib::Httpstatus and alias to Stdlib::Http::Status

Ideally we would deprecate Stdlib::Httpstatus in favour of
Stdlib::Http::Status

Support for puppet 4.5 was dropped from stdlib some time ago however the
spec tests all include an if guard to prevent them running on puppet
4.5.  As this is no longer required this PR cleans up theses guards

(MAINT) Remove testing logic for Puppet 4.5

pdksync - (maint) - Updating Contribution Guidelines

Flip "installed" and "present" in Function "ensure_packages".
Puppet-Type "package" defaults to "installed" and not to "present" (compare https://github.com/puppetlabs/puppet/blob/main/lib/puppet/type/package.rb#L148).
This Misconception lies in the Code since the most early Days.

With flipping these two Values, Rspec-Tests do not have to be adapted, when migrating from "package {}" to "ensure_packages()".
