Free disk space in release workflow

[xrstf]

Summary

This PR adds a new step to our release pipeline to free up disk space. For 0.28.2 and 0.28.3 we ran into full disks and wer not able to produce release artifacts.

The action is quite brute force, but harmless enough that building kcp and its binaries still works fine. In its current configuration it saves roughly 20GB, bringing the free space up to 42GB.
