fix(docs): rephrase backtick-in-table cell that breaks docs-build CI on dev

[tamirdresher]

Fixes the Squad CI / test job that's red on dev right now (run 27488323855, commit 567f4475).

Root cause

The skill-security-scanner.md doc landed via #1276 with a 4-backtick table cell intended to display a literal triple-backtick:

| Inside a fenced code block (```` ``` ````) | Suppressed |

That made test/docs-build.test.ts's regex /```/g see 5 occurrences across the file (the real bash example contributes 2; the 4-backtick cell's inner ``` contributes 1; the surrounding ```` contributes 2 split across opening + closing) — odd total, even-fence check fails. The same construct also tripped the "code blocks contain language specification or valid content" check.

Fix

Two-line rephrase in skill-security-scanner.md: say "three backticks" / "single backtick" in prose instead of trying to render literal delimiters in a markdown table cell. Reads cleaner anyway.

Pull request overview

Fixes docs-build CI failures on dev by removing a markdown construct that introduced an odd number of triple-backtick fence tokens, which broke the docs validation in test/docs-build.test.ts.

Changes:

• Rephrases the “Suppression” table rows to describe delimiters in prose (“three backticks” / “single backtick”) rather than attempting to render literal backticks inside a table cell.
