Slashes in markdown urls changed to %2F

[andrewmarx]

I have a few prerendered images in my articles that I manually insert in the markdown like so:

![](img/coinflipmatrix.svg)

This used to be okay and would build into:

<img src="img/coinflipmatrix.svg">

But under the most recent version of pkgdown, it's replacing the slashes with %2F:

<img src="img%2Fcoinflipmatrix.svg">

Which breaks the link. I don't know if it's actually a pkgdown issue or something else pkgdown uses. If it is pkgdown, I don't know how old my previous version of pkgdown was to narrow down when it started; it may have been very outdated.
