Update Kdevelop to 5.2.4 in Bionic

[Rik Mills]

The Kdevelop 5.2 series now has several bugfix releases that should be SRUd to Bionic

Kdevelop in Bionic = 5.2.1

5.2.3 (.2 was never released) https://www.kdevelop.org/news/kdevelop-522-and-523-released

5.2.4 https://www.kdevelop.org/news/kdevelop-524-released

These are bugfix and translation updates only, so should be appropriate to update to in Bionic. These versions already exist in Cosmic.

Unfortunately, 5.2.1 was one of the less-stable KDevelop releases in recent times, and shipped with a few significant bugs including crashes. Most of these have been fixed in the subsequent point-releases, but Ubuntu users continue to encounter (and report) them on a regular basis.
