Upgrade npm packages to their latest versions

[htdat]

From this comment #659 (comment)

Reasoning

We tried a recent round of updating npm packages in #645

However, #645 was only to update package versions that satisfy what is mentioned in package.json. That is, ^4.0.2 means npm update will only look for versions between 4.0.2 and any newer version with this format 4.x.x.

Some of packages become out-of-date very soon, for example, @wordpress/scripts(code ref) is using ^7.2.0 while its latest version is 16.1.2 (npmjs link).

@nielslange somewhat mentioned this here #645 (review)

How to do

npm does not support this by default. Instead, we need to use another package to do that.
I tried this guide https://flaviocopes.com/update-npm-dependencies/

• Install ncu https://www.npmjs.com/package/npm-check-updates
• ncu -u
• npm install
• npm audit fix

Here is the PR and its tests (I used my repo to avoid dumping so many GitHub Actions to our main repo here):
