Alertmanager API version fix(prometheus 3)

[axxyhtrx]

I got an error with that installation:

time=2024-11-17T05:52:03.562Z level=ERROR source=main.go:601 msg="Error loading config (--config.file=/etc/prometheus/prometheus.yml)" file=/etc/prometheus/prometheus.yml err="parsing YAML file /etc/prometheus/prometheus.yml: expected Alertmanager api version to be one of [v2] but got v1"

Fixed by change of alertmanager api to v2.

Hello, in addition to original bug message, I can confirm that change to v2 makes it possible to run 'prometheus' container and do not break anything.
