Add node engines fields specifying a minimum of 18

[hsubox76]

Update all appropriate package.json files in the repo to reflect a minimum Node engines version of 18.

Exceptions:

• Unpublished packages that only serve as entry points. e.g. auth/cordova, or firebase/compat/storage (the actual published package is @firebase/storage-compat).
• Types packages - FYI these are leftover from compat - all modular code should be using types within their own package.
• Auth demo apps - these are demo apps for auth testing and should be maintained by auth to the specification they want them at
• Packages that shouldn't be used in Node at all (Analytics, Installations, Messaging, Performance, Remote Config, Webchannel-wrapper)
• The template packages

Notes:

• Internal packages like component, logger, and util should be platform agnostic, but this enables us to introduce any new APIs (e.g., new cryptography API) that old versions of Node don't support, if we need to in the future
• 18 isn't necessarily the exact minimum for many of our internal tools, many of which can handle much older versions of Node, but our CI runs on 18 anyway.

The spreadsheet notes that analytics and some of the types packages aren't supported in node. I had assumed that we wouldn't see a node engines entry in those packages' package.json files..?

[hsubox76]

Yep, looks like the script didn't work, I'll fix it.

[hsubox76]

I updated the PR and also made a gist of the array in my script telling the script which packages to add this to, to make it easier for you to audit than having to go through all the files in this PR https://gist.github.com/hsubox76/e58e8a45d1cb04af7ebb31ebff07365d Let me know if any of them look incorrect.
