This is part of a series of related PRs.

• chore(reports): remove HTML-based generation and transformers #261 this PR. Removes old code that produces HTML pre-formatted automated analysis reports. Also updates the JSON response format so that rather than the new summary/explanation/description/suggestions fields being pre-combined into the old-style description field, they are kept separate.
• https://github.com/cryostatio/cryostat/pull/1685 removes code that used the HTML pre-formatted reports format in favour of exclusively serving JSON reports. Technically breaks API, but the HTML reports were unlikely to be a useful format for any other consumer than our web-client to simply display inline.
• chore(reports): remove HTML report generation cryostat-reports#137 same as above but for the reports sidecar
• feat(recordings): update Automated Analysis UI cryostat-web#1117 updates the Dashboard card implementation for Automated Analysis to use the new JSON format with separate summary/explanation/description/suggestions, and replaces the old <ReportFrame/> component that rendered the HTML reports with some reused components from the Dashboard card.
