- by default, yarn will try and fetch dependencies from the network, and
fallback to local cache if the network is down
- `--prefer-offline` switches that around so we can take advantage of
local caches before defaulting to the network
- hopefully this speeds up dependency install steps in CI
- because we now ignore git submodule changes, they didn't show up in
`git diff --cached...`, so it was possible to get submodules to be
committed
- you can re-enable submodules to be shown with `--ignore-submodules=none`
- this implements that
- we never want to allow submodules to be committed, so I've removed the
prompt for faster feedback

- we should protect against failures entering `main` which could be
avoided by running a quick unit test beforehand
- this reintroduces Lerna as it supports parallelisation and `--since`,
to run linting and unit tests on packages that have changed since
upstream

- `nodemon` doesn't properly wait for graceful shutdown if there's a job
running in Ghost when it tries to reload, so it ends up producing
errors because two versions of Ghost are started
- Node 18 added a `--watch` flag, which reloads if any required file is
changed
- switching from nodemon to this native feature should keep the
core functionality the same but fix this edge case that disrupts the
development flow
- by using the same group (the workflow name), we should be able to
limit the concurrency to 1 execution, which might help with some
flaky tests we keep seeing
- now the vast majority of our flaky tests are gone, we don't need the
bigger machines
- however, browser tests seem to be a little slow, so we can try giving
them more power than the defaults
- this should also help with resource contention when we have multiple
jobs running at the same time, as we have double the numbers of
runners on the free machines

- Firefox tests have historically been flaky in CI and a real
distraction when developing
- Firefox is, unfortunately :(, not a widely used browser at only 2.9%
of global market share
- we've not had any Firefox-specific bugs that were detected in CI for
a very long time, so it doesn't add anything anyway
- given SQLite3 is only supported for development, we don't really care about
running tests on Node versions which aren't the recommended version
- this saves 2 jobs per CI run, which helps improve the health of CI in
general
- turns out our concurrency on these 8 core machines is only 10 jobs, so
everything is running really slowly
- by opening up to `linux`, we allow executions on 4, 8 and 16 core
machines with a total concurrency of 30
- we're seeing low availability for the 16 core machines and they might
be constrained as everyone jumps to the highest spec
- in theory, we don't need super fast multi-core machines to run tests,
so I'll try with 8 core ones

- Node 18 is now LTS so we're adding support for it
- this adds Node 18.12.1 (the latest security release) to our supported
ranges and CI
