Create the plugin-descriptor programmatically

[peternied]

Description

After migrating from maven to gradle, the build script for security in OpenSearch-build was broken. We could not use the default script and had to make modifications, see opensearch-project/opensearch-build#1631

Testing

Built locally and confirmed the contents of the programmatically generated file matched the intended behavoir that was previously done by overrides, see https://github.com/opensearch-project/opensearch-build/blob/main/scripts/components/security/build.sh#L70-L71
