chore(dev): upgrade to APISIX 3.9.0

[shreemaan-abhishek]

https://github.com/apache/apisix/blob/release/3.9.0/CHANGELOG.md#390

[mstefany]

Version 3.9.0 does not work, because enable_http2 needs to be on apisix level, not on apisix.ssl.listen level:

apisix-helm-chart/charts/apisix-ingress-controller/templates/apisix-configmap.yaml

Line 58 in 6b8acad

enable_http2: {{ .Values.gateway.tls.http2.enabled }}
