The package file is introduced.

@faisal-alvi you'll want to add those files to https://github.com/10up/simple-local-avatars/blob/develop/.gitattributes so that they don't end up in the released version.

@faisal-alvi A minor suggestion, but renaming uglifyjs to build would be a better name to build the assets.

[faisal-alvi]

@claytoncollie Thanks for the suggestion, I had preserved the “build” for the actual building of the “whole project” whereas the uglifyjs is minimizing only one JS file. But as we do not have any other files to be built (for now), we can utilize the word “build”.

Odd that the previous commit passed checks but the latest failed. Given that its WP Acceptance (and that we should be setting up Cypress e2e tests here anyway) I think I'm fine with this for now (ideally we get those e2e tests in place before the next release).
