Free more disk space by uninstalling large packages

[adangel]

This removes more packages, allowing to run the "verifyPlugin" task to verify against 6 (!) IDE versions (241, 242, 243, 251, 252, 253).

Fixes #295

Once this is merged, I suggest to rerun the other open PRs (especially #298) and release a last version, that is compatible with 241. After that, we should update the minimum version (pluginSinceBuild) to at least 243 or newer. As, once 261 is released, we probably run into the disk space problem again.

Alternatively, we could skip some of the (currently) 6 version for the verifyPlugin tasks. Currently, we use recommended(), which uses all the version from pluginSinceBuild to the latest.
