- 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
fixes https://github.com/TryGhost/Toolbox/issues/532
- 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
- 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

* Correctly setup environment variable to run both local & staging browser-based tests
* Use non-production Ghost Admin build, since production builds require HTTPS to use Stripe Connect
- the create-release-branch workflow works by getting the most recent
tag, bumping it and using that to create the new tag
- now we've moved Portal into the monorepo, we've got two different
types of flags, but the Portal ones aren't valid semver so the
workflow fails if the most recent tag is one for Portal
- this fixes that by ensuring we only fetch tags matching the pattern we
use for tagging Ghost
