Markdown table syntax regression in Sarif report

[bm402]

Hello 👋

The markdown syntax in the Sarif reports produced by docker scout cves --format sarif has broken since v1.19.0.

The summary table at the end of the CVE description (found in the report at runs.tool.driver.rules.help.markdown) is no longer a valid markdown table.

Example of table in report generated by v1.18.4:
