pkgdown: report full error text (+fix url typo)

[infotroph]

Description

Seems the pkgdown job has been reportng success while failing to build data.atmosphere for a while, with the error reported as a warning that (1) doesn't contain enough information to debug it, and (2) doesn't mark the build as failed, making the deployment job just quietly remove the data.atmosphere package docs.

Here I fixed the Rd parsing error in data.atm and also refactored the build script to complain more loudly and with more diagnostic information when a package fails to build.
