eglot connector should default to using port 6005

[1player]

This code:

emacs-gdscript-mode/gdscript-eglot.el

Lines 54 to 64 in 5136be4

	(defun gdscript-eglot--extract-port (editor-settings-file)
	"Extract LSP port from Godot editor settings file."
	(when (file-exists-p editor-settings-file)
	(with-temp-buffer
	(insert-file-contents editor-settings-file)
	(when (re-search-forward
	(rx "network/language_server/remote_port"
	(* space) ?= (* space)
	(group (+ digit)))
	nil t)
	(string-to-number (match-string 1))))))

searches for the network/language_server/remote_port setting in the editor settings file, which is only present if it has been modified from the default value. So, unless you have changed the remote port manually, it will not work.

By default (at least as of 4.4), Godot listens to port 6005, so we should default to that if the regex doesn't return any result.
