chore(fs): Template for multi module projects

[shub-est]

Description

I use trivy to scan source code directly and wanted to generate HTML report. The current template is catering to image scanning and does not provide context for what directory the CVEs are from

Using the existing html.tpl
open-api-generator-report-original.html

Using the new template
open-api-generator-report-new-template.html
