feat(version): Upgrade to Copilot 1.40.0

[knilink]

update lsp to 1.40

• added initialized notification which required by later lsp server
• updated script entry from agent.js to language-server.js, assuming not supporting backward compatible since copilot.el enforcing copilot-node-server's version

i am not subscribing copilot and only tested with modded lsp server based on copilot.vim so may need someone else help testing it

P.S.
proposed copilot-node-server to add executable entry point jfcherng/copilot-node-server#17
so start from next release the server should be easily started by npx -y copilot-node-server@1.40.0 --stdio therefor can consider simplify the installation and version management later

FWIW (I am not part of the copilot-emacs project but just an avid user), the upstream copilot.vim project renamed the agent.js file to language-server.js in the 1.34.0 release, so you will also need to update the references to this as well in copilot--server-executable - but otherwise I tested this briefly and it works for me! Thanks.

Yes, this kind of issue can be avoided by @knilink's proposal. It can be directly dealt at https://github.com/jfcherng/copilot-node-server/blob/a4a18ba57b6a21c416c60b6037e46c177529ac10/package.json#L6 if the user uses npx to start the server.
