Instructions on package.publish could be more clear

[flip111]

You can get this error when trying to publish

Did not find publishing config: add a valid one in package.publish

It's not clear here what to do. Initially the docs say to follow this instruction so this should be self explanatory. One should add a publish section to the configuration. Configuration explanation can be found here https://github.com/purescript/spago#the-configuration-file

Yes, we should link to that section, but we could also print out an example publishing config, maybe even including the package location as you suggest in #1060
