NNPDF/nnpdf: Version 4.0.4

This is an incremental bugfix release.

The main highlights are:

• Fix a bug in integrated luminosity plots #1442.
• Code for ancillary NNPDF 4.0 analysis (such as Hessian conversion #1344, Nf=4 re-evolution #1422, or alpha_s errors bundling #1340).
• User facing documentation, including for reproducibility of 4.0 the analysis (#1378)

Additional changes include:

• A bug in the evolution basis definition #1445, of no consequence to existing analyses was fixed (thanks to @msyan!).
• Enhancements to hyperoprimization allowing it to work on estimators depending on a full fit (#1316).
• Some work on moving features implemented in C++ to python (e.g. #1268).
• Tweaks and enhancements to various plotting functions, as well as new spider diagrams (#1194).
• Automation using Github Actions, to for example produce release Doceker images (#1390).
