Eglot: declare eglot-lsp-context bound to non-nil

Otherwise, it'll be really hard to use it in the recommended fashion:

  (defun my/project-find-function (dir)
    (when-let ((match
                (and (bound-and-true-p eglot-lsp-context)
                     (locate-dominating-file dir "some-marker-file"))))
      `(transient . ,match)))

  (add-hook 'project-find-functions #'my/project-find-function)

because 'bound-and-true-p' will never return t even when the hook is called
from eglot--current-project.
