databases/R-cran-RSQLite: Update from 2.4.0 to 2.4.6

This update fixes a build failure with math/R 4.6.0. R 4.6.0 switched
the default C++ standard to C++20. This exposed an issue in the plogr
dependency (plog/Record.h). Upstream resolves this in 2.4.6 by removing
the plogr dependency entirely. The bundled SQLite was also updated from
3.50.0 to 3.51.2.
