Require Jenkins 2.346.3 or newer

60% of installations of the most recent release of the plugin (now 9 months old) are running Jenkins 2.346.1 or newer based on the install stats. Jenkins 2.346.3 is a good choice as the last LTS version before Jenkins core requires Java 11.

• Remove unused exclusion
• Require Jenkins 2.346.3 or newer
• Test with nested view plugin 1.26

Resolves a GitHub false positive warning about the nested view plugin 1.24 vulnerability. Since the nested-view plugin dependency is only in test scope, vulnerabilities in that plugin do not affect this plugin.
