* bug#67463: 30.0.50; Eglot may manage js-json-mode buffers with wrong server

It seems that buffers in `js-json-mode', the default mode for JSON
files, could be wrongly managed by JavaScript language servers of Eglot,
perhaps because:

  - `js-json-mode' is derived from `js-mode';
  - Eglot uses `provided-mode-derived-p' to determine whether a buffer
    should be managed by a server.

Here is a recipe to reproduce the problem I encountered:

  1. Install Node.js[0] and NPM[1]. (Sorry, but I could not find an
     easier way to set up the environment. They may be installable with
     your system's package manager.)
  2. mkdir /tmp/repro && cd /tmp/repro
  3. npm install typescript typescript-language-server (This will install
     the language server locally in the directory.)
  4. emacs -Q
  5. C-x C-f main.js RET
  6. C-u M-x eglot; enter "npx typescript-language-server --stdio"
  7. C-x C-f package.json RET (This file is automatically created by
     `npm install'.)

I expect that the 'package.json' buffer is not managed by Eglot, but it
is actually managed by typescript-language-server, which does not really
understand JSON and is reporting some invalid errors.

Thanks!
