Error in action release-please.yml

Problem with this file:
https://github.com/istanbuljs/istanbuljs/blob/master/.github/workflows/release-please.yml

Error when evaluating 'strategy' for job 'publish'. .github/workflows/release-please.yml (Line: 24, Col: 15): Matrix vector 'path' does not contain any values

See pull #673 for an example. Don't have any XP for this sort of silliness or I would fix it myself :(

it seems that actions just don't like the empty output when there are no packages to publish, probably an additional conditional statement would fix.

@bcoe
In the current situation, the istanbul-lib-instrument package needs to publish; see pull #673 which is still open from a week ago.

Last package was published 3 weeks ago when I fixed the downstream coverage map bug in the reports.
No idea how to test the yml action on my current setup. Please think of just fixing and testing this yourself :)
