Typo in pNotUsedAsHeader

[AnnaTomanek]

Is:

description:
    en: "Headers like <code>h1</code>. h6 are extremely useful for non-sighted users to navigate the structure of the page, and formatting a paragraph to just be big or bold, while it might visually look like a header, does not make it one."

Should be:

description:
    en: "Headers like <code>h1</code> - <code>h6</code> are extremely useful for non-sighted users to navigate the structure of the page, and formatting a paragraph to just be big or bold, while it might visually look like a header, does not make it one."
