this was a problem before the recent clean-up; the only reason it just decided to show now is because 2000+25 is valid PHP code, so PHP saved our asses.
PHPStan failed on 7.4 after updating to 0.12.99, and I figured it was less hassle to just do this than fix the build. In any case, we stopped shipping 7.4 months ago, and warned at 3.22 release that 7.4 support would soon be dropped.
7.3 isn't actively tested anymore, and since 7.4 has been out for so long already, it doesn't make sense to keep pandering to users who can't be bothered to update their PHP binaries.
In most cases, these users are also experiencing problems caused by older versions of pthreads that were long since fixed.
In addition, pthreads is no longer tested or supported on 7.3, so users can't get newer bug fixes even if they wanted to.
we can't safely use `ubuntu-latest` because the build caches will break if they were built for 18.04 and used on 20.04, or vice versa. Instead, we pin the images (and caches) to a specific version.
