Set prometheus adapter version

[hanzjk]

Purpose

Describe the problems, issues, or needs driving this feature/fix and include links to related issues in the following format: Resolves issue1, issue2, etc.

There is an unintended bug in OpenChoreo where it pulls the latest adapter image by default, even when a specific module version is provided. As a workaround, we had to explicitly set the adapter version. This issue was not detected earlier because the latest image earlier was working fine.

However, the latest image has since changed, and the metrics-adapter-prometheus pod is now failing with a configuration error. Therefore, we have explicitly set the adapter version.
