[aws-cloudwatch-metrics] fix: update enhanced_container_insights template from string to boolean

[kangadrewie]

Issue

This value was being passed as a true string which was not been handled or considered in the CW Agent and was ultimately ignored.

Related issue - aws/amazon-cloudwatch-agent#1030

Description of changes

Modified the template to not wrap the boolean as a string.

Checklist

• Added/modified documentation as required (such as the README.md for modified charts)
• Incremented the chart version in Chart.yaml for the modified chart(s)
• Manually tested. Describe what testing was done in the testing section below
• Make sure the title of the PR is a good description that can go into the release notes

Testing

Updated ConfigMap generated by this helm to have true instead of "true". Applied changes and rolled out new daemonset resulting in Enhanced Observability metrics being sent to CW.
