Modify NIX and keyserver configuration files to allow node version >= 18
Summary:
This differential applies temporary solution to allow usage of node version >= 18 since it is necessary for current project regarding blob service and big notifications.
The solution is not perfect and the correct one will be implemented in future: https://linear.app/comm/issue/ENG-4373/revert-to-using-nvm-to-lock-into-specific-node-version
Test Plan:
- run yarn cleaninstall
- run nix develop
- run node --version and expect the output to match 18.12.1
