Redmine

CI lint is failing because bundle-audit reports a vulnerability in nokogiri 1.18.x (GHSA-wx95-c6cv-8532).
This patch updates the dependency requirement to nokogiri v1.19.1 or later to address it.

Verified that tests pass after the update: https://github.com/farend-biz/redmine-dev/actions/runs/22343849608
