Thanks to Thomas and Denis,

That's it: use GFS Didot for the French text and Theano Didot for the 
Greek. In my working text I have this preamble (and other things):

\setuplanguage[fr][patterns={fr,agr}]
\mainlanguage[fr]
\setcharacterspacing[frenchpunctuation]]
\setuplayout [backspace=40mm]
\setuppagenumbering[alternative=doublesided, location={header, inmargin}]
\setupmargindata[inmargin][location=inner, 
style={setupinterlinespace[line=2.8ex]}]
\setupmarginframed[inmargin][align=right]
\setupbodyfontenvironment[default][em=italic]
\definefallbackfamily[mainface][rm][Theano 
Didot][preset=range:greek,force=yes]
\definefontfamily[mainface][rm][GFS Didot]
\setupbodyfont[mainface, 11pt]

I'm currently working on MS Windows 11 for the moment (as a test beside 
Linux). I didn't try to compile this text under Linux, but I don't think 
there is an issue with the OS.

As far as GFS Didot is concerned, I have installed the most recent 
version. But what amazes me the most is that by only keeping a font like 
EBGaramond without writing :
\definefallbackfamily
  [mainface]
[rm]
[Theano Didot]
[preset=range:greek,force=yes]
So, using EBGaramond only, I have the French text (with italics), as 
well as the Greek text...

Try this :

\setuplanguage

\mainlanguage[fr,agr]

\definefontfamily

[mainface]

[rm]

[EBGaramond]

\setupbodyfont[mainface, 12pt]

\setupbodyfontenvironment[default][em=italic]

Socrate est descendu au Pirée et affirme sa satisfaction du culte rendu

rien des prières} qu'il a lui-même rendues à la déesse avec les autres 
participants, dont il fait pourtant état. Sur le chemin du retour, il 
est arrêté par Polémarque qui leur apprend qu'une retraite aux flambeaux 
à cheval est prévue par les Thraces, ainsi qu'une fête de nuit 
\quote{qui vaut la peine d'être vue} (ἣν ἄξιον θεάσασθαι; {\em èn

I've found a solution, with Segoeui (Windows font) as the main font and 
Theano Didot for the Greek text.
But I don't understand why setting the fonts to GFS Didot and Theano 
Didot prevents italics from being displayed ...

If you want the Greek displayed in Theano, you will have to add “force=yes” to your definition of the fallback family:
