I don't think it makes much sense to add this specifically for
Eglot, indeed.  It might make sense OTOH to add to the Help menu an
entry that lets you jump directly to the docs relevant to the current
modes.

It could be a submenu generated by considering the list of all currently
active minor modes (buffer-local and global) plus the current major mode
(and its parents, maybe?) and for each one of them try and find out
where they might be documented (e.g. relying on a symbol property
to map a mode to its Info node?).
