Bug 1874627 - regenerate expiring test certificates for 2024 (branch patch), this time with certificates included. r=jschank a=test-only


* the certificates were regenerated using `./mach generate-test-certs`
* the build/pgo/certs/ changes were made using
  `./mach python build/pgo/genpgocert.py`
* the zip files in security/manager/ssl/tests/unit/test_signed_apps/ were
  updated per the directions in the corresponding moz.build file
* security/manager/ssl/tests/unit/test_cert_override_read.js needed manual
  updating

These certificates and other test artifacts will now expire in 2025.
