Upgrade to node 18

[jkasten2]

Description

1 Line Summary

Update from Node 14 to Node 18 (LTS).

Details

Updated node versions used in docker and the CI / CD process. Had to upgrade to bundlesize2 as bundlesize was incompatible with node 18.

Validation

Tests

Tested yarn build:dev-prod ensuring it works with Chrome on Windows to subscribe and get a notification.
Ensured yarn build:prod builds and bundlesize detects going over its size limit. yarn lint and yarn test pass as well.

Checklist

• All the automated tests pass or I explained why that is not possible
• I have personally tested this on my machine or explained why that is not possible
• I have included test coverage for these changes or explained why they are not needed

Programming Checklist
Interfaces:

• Don't use default export
• New interfaces are in model files

Functions:

• Don't use default export
• All function signatures have return types
• Helpers should not access any data but rather be given the data to operate on.

Typescript:

• No Typescript warnings
• Avoid silencing null/undefined warnings with the exclamation point

Other:

• Iteration: refrain from using elem of array syntax. Prefer forEach or use map
• Avoid using global OneSignal accessor for context if possible. Instead, we can pass it to function/constructor so that we don't call OneSignal.context

Checklist
