Fix LocalizedLandmarkType for contentinfo aria role and <footer> scoped to body

Change the LocalizedLandmarkType and LocalizedControlType for the
contentinfo aria role from "content info" to "content information" per
https://www.w3.org/TR/core-aam-1.1/#role-map-contentinfo.

Also update the LocalizedLandmarkType for <footer> when scoped to the
body element to "content information", since it inherits this from
the contentinfo role per https://w3c.github.io/html-aam/#el-footer.

Note that this doesn't affect <footer>'s LocalizedControlType,
which should be "footer" (but is currently still "content info").
That is handled in the separate change at
https://chromium-review.googlesource.com/c/chromium/src/+/1763243.
