Subject: [PATCH] fix: align otel-collector image tag with chart appVersion

The otel-collector image tag was hardcoded at 2.19.0 while the chart
appVersion is 2.27.0. The 2.27.0 app pushes an OpAMP config containing
a `json:` key in the ClickHouse exporter, which the 2.19.0 collector
binary rejects with:

  'clickhouseexporter.Config' has invalid keys: json

This causes an immediate CrashLoopBackOff on my-clickstack-otel-collector,
making port 4318 unavailable to any downstream collectors.

Fixes #219
