Remove duplicate \cr

[yutannihilation]

Close #6509

Currently, the generated \tabular for "Aesthetics" section uses double \cr. But, guessing from what is described in WRE, it's unnecessary.

... The second argument consists of an arbitrary number of lines separated by \cr, and with fields separated by \tab. For example:

  \tabular{rlll}{
    [,1] \tab Ozone   \tab numeric \tab Ozone (ppb)\cr
    [,2] \tab Solar.R \tab numeric \tab Solar R (lang)\cr
    [,3] \tab Wind    \tab numeric \tab Wind (mph)\cr
    [,4] \tab Temp    \tab numeric \tab Temperature (degrees F)\cr
    [,5] \tab Month   \tab numeric \tab Month (1--12)\cr
    [,6] \tab Day     \tab numeric \tab Day of month (1--31)
  }

This was added in #6285, but I found no particular reason. So, I guess we can just remove this.

Thanks @yutannihilation for taking this on! Does the pkgdown site look normal now? I always forgot what I can and can't preview with pkgdown

[yutannihilation]

It seems fine! This is the local preview by pkgdown::build_site().

[yutannihilation]

This is the local preview of ?geom_hex. This also looks fine.

Ah yeah that looks great, thank for posting the pictures! I honestly can't quite recall why I put two \cr there, but this is a great improvement.

[yutannihilation]

Thanks for approving! Let's merge and see if this fixes the actual pkgdown site.

I checked several pages on the pkgdown site, and all look fine now 🎉

Yeah looks much better, thanks! 🎉
