Archive PloneConf 2025, prepare for PloneConf 2026

The following tasks need to be performed to archive a snapshot of the trainings from PloneConf 2025 and prepare for PloneConf 2026. @stevepiercy, @polyester, and others will perform these tasks.

• #1004
• Cut branch 2025 from main
• Add 2025 to the Ruleset "Branch protection" in https://github.com/plone/training/settings/rules/20865105.
• Create environment 2025 at https://github.com/plone/training/settings/environments.
  • In the environment 2025, create environment variable DEPLOY_PATH_TRAINING to use the path on the server /var/www/2025.training.plone.org. The other variables and the secret are inherited at the repository level. The secret DEPLOY_KEY_TRAINING is stored in our REDACTED_SECRET_STORAGE_TOOL, and its name is "dplone_training_rsa kupu training user deploys github DEPLOY_KEY_TRAINING".
  • In the environment 2025, add deployment branch rule 2025 with the pattern of 2025.
• Add a new key for 2025 in https://github.com/plone/ai-team-private/blob/master/ansible/host_vars/kupu.yml#L109-L115. (@fredvd plans to migrate this old Ansible deployment configuration to a modern one.)
• Configure DNS for 2025.training.plone.org
• Configure web server for 2025.training.plone.org
