empty-table-header is documented as being able to fail despite specifying reviewOnFail: true

[dbjorge]

rule-descriptions.md documents the new empty-table-header rule as having Issue Type failure, needs review, but I think this should probably just be needs review based on the rule's config specifying "reviewOnFail": true and the rule only having pass/incomplete integration test cases.

Product: axe-core

Expectation: Docs should match config/tests

Actual: Docs and config/tests don't match

Motivation: We'd like to understand whether the docs vs the implementation are the intended behavior, so we can adjust our documentation/ruleset accordingly in Accessibility Insights

axe-core version: 4.2.0
axe-webdriver, extension or other integration version: n/a

Browser and Assistive Technology versions: n/a

For Tooling issues:
- Node version: n/a
- Platform:  n/a
