Plone 5.2.4 installer

Hi team,

Can we have an installer for 5.2.4?
Probably PR #110 needs to be merged first, if that is deemed good enough.
Some links:

- Versions: https://dist.plone.org/release/5.2.4/versions.cfg
- pip constraints: https://dist.plone.org/release/5.2.4/constraints.txt
- Launchpad: https://launchpad.net/plone/5.2/5.2.4
- Release page on plone.org, private for the moment: 
https://plone.org/download/releases/5.2.4

I have added an issue with the same text: 
https://github.com/plone/Installers-UnifiedInstaller/issues/112
Does it make sense to only create an issue from now on? It makes the 
process more public, so people can see the progress.

Cheers,
