fix(charts): Get minio secrets from Values

[reggermont]

What

Applying the helm chart is failing with the following error:

STDERR: Error: template: airbyte/templates/env-configmap.yaml:41:37: 
executing "airbyte/templates/env-configmap.yaml" at <include "airbyte.minio.accessKey.password" .>:
error calling include: template: no template "airbyte.minio.accessKey.password" associated with 
template "gotpl"

It happens because the method doesn't exist in the _helpers.tpl. But the value exists in the Values.yaml

How

Just replace calls to methods to values instead, and enjoy the full power of helm!

🚨 User Impact 🚨

None. Applying the fix will at the contrary improve helmers' life
