add printf style formatting to Rf_error calls

[spotaws]

Description

This change adds prinf style formatting to Rf_error calls. Without this, compilation fails when -Wformat-security is passed to gcc.

/home/spot/git/libsbml/libsbml-5.20.2/build/src/bindings/r/libsbml_wrap.cpp:330601:17: error: format not a string literal and no format arguments [-Werror=format-security]
330601 |         Rf_error(e.what());
       |         ~~~~~~~~^~~~~~~~~~

I have tested this in Fedora 41 (Rawhide) against gcc-14.0.1 and R 4.4.0 and it resolves the "Fails To Build From Source" issue.
