docs: update deprecated server types (#718)

The CX Gen 2 and CPX Gen 1 types are deprecated and will be removed from
the API at the end of the year. This replaces all usages in our docs, so
users do not have to figure it out themselves.

Changelog Entry: https://docs.hetzner.cloud/changelog#2025-10-16-server-types-deprecated
