CI: Use pcre2-devel instead of pcre-devel in dockers

[seisman]

pcre2-devel is not available in Fedora:rawhide. That's why the docker CI fails.

This PR updates prec-devel to prec2-devel, according to https://www.pcre.org/.

There are two major versions of the PCRE library. The current version, PCRE2, released in 2015, is now at version 10.47.

The older, but still widely deployed PCRE library, originally released in 1997, is at version 8.45. This version of PCRE is now at end of life, and is no longer being actively maintained. Version 8.45 is expected to be the final release of the older PCRE library, and new projects should use PCRE2 instead. However, it's still found in various legacy systems and some platforms, including certain services that continue to use the original PCRE for compatibility reasons.
