1. fonts-x-org: Remove Adobe’s Helvetica fonts confusing pdf.js used by … …

   …Firefox
   
   This works around a Mozilla Firefox regression from 114.0 to 115.0.
   Firefox was upgraded from 114.0 to 115.0 around July 5th, 2023, and
   until now we had two problem reports. It’s actually a [regression][1]
   [in][2] [pdf.js][3], used to display PDF files inside the browser.
   Evince or other PDF viewers do not have the problem.
   
   The problem is, that for PDF documents using Helvetica, but not
   embedding the font, pdf.js chooses the X.Org font, despite Fontconfig
   matching *Helvetica* to *Nimbus Sans L*:
   
       $ fc-match Helvetica
       n019003l.pfb: "Nimbus Sans L" "Regular"
   
   As downgrading Firefox from 115.0.2 to 114.0 is unsupported by Mozilla
   for profiles – a warning is shown, and you need to start it with
   `--allow-downgrade` – remove the likely unused Helvetica fonts confusing
   Firefox/pdf.js.
   
   Resolves: #2933
