Eglot: fix signature's of Eglot's ElDoc functions

These functions are specified to be passed at least one
argument, so our implementation must accept an arbitrary number
of arguments.

* lisp/progmodes/eglot.el (eglot-signature-eldoc-function)
(eglot-hover-eldoc-function): Fix signature.

(cherry picked from commit aa94e1c56c1b4aeb2e2c98f3b7ccbc354f50108e)
