Fix Grunt task responsible for upgrading certificate dependency

[desrosj]

Because an exact version is pinned for composer/ca-bundle, the composer update command cannot update the dependency to the latest version.

The command would not work for an individual dependency anyway due to the fact that there is no composer.lock file generated.

This also updates the workflow that tests the build process to verify that the certificate related files in src/wp-includes/certificates affected by the Grunt tasks are up to date.

What's the bet way to test this? Manually downgrade composer/ca-bundle and then run npm run grunt certificates:upgrade-package?

[desrosj]

That's right.

• rm -rf vendor
• Change pinned version to any earlier.
• Run composer update, npm run grunt copy:certificates and npm run grunt build:certificates to put the old version in Core appropriately. Make note of the files changed in version control.
• npm run grunt certificates:upgrade.
• The changed files under version control should disappear because it should update to the latest version.
• npm run grunt certificates:upgrade should succeed and output "latest version already installed."
