This Article has been updated at the authors’ request following the realisation that the DFT+DMFT calculations presented are not fully charge self-consistent due to a minor bug in the workflow. The corrected code may be obtained at [https://doi.org/10.5281/zenodo.8308203]. All results presented in this Article remain valid and may be interpreted as being very close to one-shot DFT+DMFT calculations. The cRPA calculations of the interaction parameters presented in Fig. 3 are completely unaffected.
