Update Conan package revisions (#4033)
Update Conan package revisions (#4033)

The non-corp build started failing due signature mismatch when
downloading the libjpeg library archive. Updating to the latest
revision found on https://conan.io/center/libjpeg fixes the issue.
Also, the pcre2 10.33 package was referencing a server that no longer
exist, update to 10.40.
