yPackages upgrade + minted fix + README update

I still have some issues with bmc-boxes

/home/[USER]/texmf/tex/latex/BMC/bmc-boxes.sty:76: Package pgfkeys Error: I do not know the key '/infoBulle/icon/radius/.store as dimen' and I am going to ignore it. Perhaps you misspelled it.

See the pgfkeys package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.76 }

I feel like it merges two different lines but cannot see why, there is a second error of the same kind on line 89.

Also, this PR relates to #14 and parts of #11

Together with this PR and uncomment \RequirePackage{etoolbox} in bmc-fonts.sty, bmc-color.sty and bmc-ref.sty I manage to build on macOS with textlive 2022.

Hmm, I'm not sure about the LuaLaTeX requirement. I like that it worked with pdfLaTeX.
