> The currently recommended certificate chain as presented to Let’s Encrypt ACME clients when new certificates are issued contains an intermediate certificate (ISRG Root X1) that is signed by an old DST Root CA X3 certificate that expires on 2021-09-30. In some cases the OpenSSL 1.0.2 version will regard the certificates issued by the Let’s Encrypt CA as having an expired trust chain.
>
> Most up-to-date CA cert trusted bundles, as provided by operating systems, contain this soon-to-be-expired certificate. The current CA cert bundles also contain an ISRG Root X1 self-signed certificate. This means that clients verifying certificate chains can find the alternative non-expired path to the ISRG Root X1 self-signed certificate in their trust store.
>
> Unfortunately this does not apply to OpenSSL 1.0.2 which always prefers the untrusted chain and if that chain contains a path that leads to an expired trusted root certificate (DST Root CA X3), it will be selected for the certificate verification and the expiration will be reported.

This backports several build and test tool improvements to the 5.4 branch. Most notably, this includes:
- The changes required to allow each workflow to be triggered by the `workflow_dispatch` event so that tests can be run on a schedule [50590].
- The ability to run PHPUnit tests from `src` instead of `build` [50441-50443].
- Splitting single site and multisite tests into parallel jobs [50379].
- Split slow tests into separate, parallel jobs for PHP 5.6 [50444].
- Better branch and path scoping for GitHub Action workflows when running on `pull_request` [50432,50479].
- Several `devDependency` updates.

This updates the 5.4 branch to support the latest LTS version of NodeJS (currently 14.x), allowing the same version to be used across all WordPress branches that receive security updates as a courtesy.
In addition to backporting the package updates that happened after branching 5.4, dependencies that were removed in future releases have also been updated to their latest versions.

This introduces the `LOCAL_PHPUNIT` environment variable, which allows the desired version of PHPUnit to be specified when running the PHP tests within the local Docker environment.
Because support for newer versions of PHPUnit is not backported, some versions of PHP need the ability to run multiple versions of PHPUnit for different branches. This adds the flexibility needed to use the Docker environment within those older branches to run the PHP tests.

This ensures that the image used as a default site icon looks good on a dark background.
The image was previously changed in the `wp-admin` directory, but the site icon is now loaded from `wp-includes`.
