When using Eglot with ocamllsp (or other language servers built with the
same OCaml LSP server library), M-x eglot-shutdown sends an invalid
JSONRPC request to the language server and causes it to exit with an
error message instead of gracefully.  As an additional side effect of
the error, eglot will restart/reconnect to the language server instead
of staying disconnected.

1. emacs -Q
2. C-x C-f ~/temp.ml
3. M-: (setq major-mode 'tuareg-mode)
4. M-x eglot
5. C-u M-x eglot-shutdown

This produces the following *Messages*:

    [eglot] Connected! Server `ocamllsp' now managing `(tuareg-mode caml-mode reason-mode)' buffers in project `azeng'.
    [eglot] Asking EGLOT (azeng/(tuareg-mode caml-mode reason-mode)) politely to terminate
    [jsonrpc] Server exited with status 1
    jsonrpc-error: "request id=5 failed:", (jsonrpc-error-code . -1), (jsonrpc-error-message . "Server died"), (jsonrpc-error-data)

And from the events buffer:

It seems that jsonrpc.el is sending a "null" value for the params field
of a request, when it should instead be omitting the field or sending an
empty JSON object instead:
https://www.jsonrpc.org/specification#parameter_structures

Users of other editors have reported similar issues, and concluded that
this was correct (if pedantic) behavior by ocamllsp and should be fixed
in the editor: https://github.com/helix-editor/helix/issues/5400
