Allow lts for the LTS, and allow pre for the latest pre-release (#234)

* update tests to latest `versions.json`

* allow specifying the version as `lts` to install the latest LTS version

for now, this just hardcodes the LTS version in the source (similar to how juliaup does it) since the latest LTS is not available in `versions.json`. Since the LTS is updated so rarely this might be ok for now.

* add a 'pre' version

* Run `npm ci` followed by `npm run build`

* Add a CI job to test `pre`
