PR: Unexpected output from `luaotfload` about a loading delay

[Paebbels]

When translating a documentation generated by Sphinx, I see these messages at the LuaLaTeX startup phase when loading LaTeX packages:

(/latex/.miktex/texmfs/install/tex/latex/base/size10.clo
luaotfload | db : Font names database not found, generating new one.
luaotfload | db : This can take several minutes; please be patient.)))
(/usr/local/share/miktex-texmf/tex/latex/cmap/cmap.sty)

Question:

• Should luaotfload be executed when building the Docker image to prevent this message (and save time)?
