Smoke tests are all failing because they lack libpcre2

But this doesn't change anything in smoke.yml...? 😕

Ah, so the 1.7.3-build image does not include libpcre2. But 1.7.2-build does because we updated them after the release.

I don't know why that only breaks smoke tests, though. This should affect all specs that build the compiler in the 1.7.3 image. 🤷
Guess we need to re-publish the 1.7.3-build images with crystal-lang/distribution-scripts#219 as well. I thought we had updated the 1.7 branch with that, but apparently not.

FTR: It's not just smoke tests, but actually all linux jobs that make use of the build docker image.

It should be fixed now. The -build docker images have been updated to include libpcre2.
