Make Ruler/Alertmanager easy for new users

[friedrichg]

Is your feature request related to a problem? Please describe. Users have trouble using ruler and alertmanager, because it provides too many modes of operation.

Describe the solution you'd like We should make clear in the docs how a new user should use ruler and alertmanager and what options not to use (deprecated)

Hi @friedrichg , I found some doc references for alertmanager configuration:

• https://cortexmetrics.io/docs/guides/alertmanager-configuration/.
• https://cortexmetrics.io/docs/configuration/configuration-file/#alertmanager_storage_config
• https://github.com/cortexproject/cortex-tools?tab=readme-ov-file#alertmanager

Could you please elaborate on what operation modes are you talking about
