This significantly speeds up `yarn lint` for me. It also ensures we’re
listing all source files in the project, including the `.eslintrc` files
and any other files that may be present.

- New linter rules are now added
- Perhaps the `createPayee` method i've tagged with a disable should be
deleted.
- I have ignored unused methods in Plaid/Mobile as this stuff is still
WIP/experimental?

After #1115, new Node.js versions will be able to be used for
development of the frontend. This PR changes the recommended Node.js
version to 18 (the current LTS version). I have also tested with 16 and
20 and it works.

I also took the opportunity to:

- move the build script that was at the project root to the `bin/`
folder
- update the `browserslist` to target Electron 24 (which is the version
we currently build against). This results in a slightly smaller bundle
due to no longer having to transpile optional chaining.

1. Upgrade all `cross-env` versions to be the same
2. Added `cross-env` to `desktop-electron` - it was used there, but was
missing as a dep

Updates to the latest version of electron and moves the backend-frontend
communication from node-ipc to websockets. This resolves the previous
roadblock regarding `nodeIntegration` .

Done

- Remove node-ipc in favour of websockets. 
- Move file copying out of `preload.js` to avoid importing module `fs`
there
- Bump all electron pacakge versions to the latest
- Added new package for finding open ports as node-ipc is gone
- Tweaked webpack config for above changes


Partially fixes #468

Questions/ Pending:
- Literally every single test fails for me, presumably some issue with
my setup/environment.
- The websocket communication is not using TLS. I'm not sure how to
enable this, or if we even need to as its all local.
- Still need to create the CI for building/deploying but I'm not sure
where start in this regard as i have no exp with it. Presumably we will
need to point the electron auto-updater to the github releases url's. If
people are happy with this PR I will look at adding the CI before its
merged.
- In dev mode only, I have disabled TLS security becuase my docker
container's cert is not signed. I _assume_ this will be true for other
people who spin up the server on thier own hardware. Perhaps I just need
to change my cert to one from letsencrypt or something...

Notes.
I have not touched javascript in eons so my apologies if the commit
trail is a bit fragmented. I tried to keep them fairly contained and
then there is a slightly gnarly final commit fixing all the linter
issues... Please let me know if you want me to squash some commits etc.

I initially tried to move this to web workers the same way the web app
does it but this was unsuccessful. I have found no way to spin up a
worker in one place (frontend/backend) and then pass this worker to the
other. The electron ipc channels don't allow you to directly pass
objects such as workers, everything is cloned/serialised. Passing a port
number so the other end can spin up its own socket works fine.

```

What’s changed:

- `loot-core` did not have a `browserslist` config, so
`@babel/preset-env` assumes we want to [transpile all the way back to
ES5](https://babeljs.io/docs/options#no-targets). I’ve removed the
`browserslist` config from each of the `package.json` files and moved it
to the root so this doesn’t happen again.
- I updated the target from `electron 3.0` to `electron 12.0` to match
our Electron dependency
- I’ve added `defaults` (currently equivalent to `> 0.5%, last 2
versions, Firefox ESR, not dead`) which is [recommended by
browserslist](https://browsersl.ist/#q=defaults). We could consider
tightening this, but it doesn’t offer a ton of space savings at this
point to just target Electron 12.
- Since much less transpilation will be happening, stack traces (dev and
prod) will be much easier to read!
