  package › Every rule has a doc with the appropriate content

  test/package.mjs:134

   133:     if (!RULES_WITHOUT_PASS_FAIL_SECTIONS.has(ruleName)) {              
   134:       t.true(documentContents.includes('## Pass'), `${ruleName} include…
   135:       t.true(documentContents.includes('## Fail'), `${ruleName} include…

  prefer-map-has includes '## Pass' examples section

  Value is not `true`:

  false
