[Tests] Update gdtools to 0.5.2 in renv.lock (#15124)

gdtools 0.5.2 reached CRAN on 2026-10-15. `tests/renv.lock` pins 0.5.1 from the moving P3M `cran/latest` URL, so P3M no longer serves a macOS arm64 binary for 0.5.1 (`gdtools_0.5.1.tgz` is a 404, `gdtools_0.5.2.tgz` is served).

renv then falls back to the source tarball, and compiling it on the macOS runners fails with `ld: library 'intl' not found`. `flextable` fails with it as a dependent, which stops `renv::restore()` and makes the macOS jobs of the built-version nightly fail before running any test.

A targeted update to 0.5.2 gets the binary back. No other package changes.
