npm.sh: reenable updating `npm` to latest version
The command started working for some reason, I don't know why. See https://phabricator.wikimedia.org/T371873#10044743
Note that the -L
flag for cp
is something I previosly forgot to
commit, but it's not the cause of the error mentioned in T371873. In
the case of T371873, the original problem was related to some kind of
dependency version incompatibility.
