build: use keywords instead of keyword in package.json

[amtrack]

Thanks for this awesome plugin. I'm using it in several projects!

I'm working on a website for exploring awesome sfdx/sf plugins and was wondering why it didn't show sfdx-git-delta.

LGTM !

Thanks for this contribution in the plugin visibility

I changed the title to "build" instead of "fix" to avoid creating a release candidat PR and avoid having this listed in the release note as it is not a feature nor a fix for the plugin itself
