- this reverts commit 48dda23554
- also includes a resolution for `@elastic/elasticsearch` so we don't
run a version that is potentially problematic - see referenced issue
for context
- up until now, we've been sending the `safe` version as data in
metrics, but this only includes major.minor
- we'd like to be able to see how every release affects the results, so
this commit switches to using the version that was supplied in the
package.json so we've got more of a granular overview
refs https://github.com/TryGhost/Toolbox/issues/354
- this commit turns the Ghost repo into a monorepo so we can bring our
internal packages back in, which makes life easier when working on
Ghost
