Downgrade pureconfig-exercises version

[paualarco]

There was some issues in the past on the deployment of pureconfig exercises, noticed that the selected version did not even existed. Hence it was downloaded to 1.2.0

Indeed, there has been with the publishing of the last few releases of exercises-pureconfig. It seems like the scala jar is not on the classpath: https://github.com/scala-exercises/exercises-pureconfig/runs/966737129?check_suite_focus=true#step:9:292.

ah that might be due to incompatibilities between 2.12 and 2.13 artifacts.

Maybe we are in the following case: scala/bug#11832 (comment), I noticed that sbt-exercise has 2.13 in crossScalaVersions:

wdyt @juanpedromoreno ?

I think the last releases failed because of this issue. I couldn't spend time on it, but I hope to do it shortly.

The problem with the pureconfig exercises would be elsewhere, probably because the scaladoc comments are not completely valid, but couldn't figure it out when I looked into it :( .

Ok I see... thought that the last time the pipeline was not even succeeding. So I guess we should fix the release for exercises-pureconfig first.
It's strange that the Eval exercises were successfully released whereas the OptionT that was added one commit later did never get released...
