Update addons-linter to 5.25.0

[Sancus]

Our version is almost a year old at this point, we should update to the newest.

Here's an example of this: https://github.com/thundernest/addons-server/commit/ef373a3ca15f4a168282f15334fcc1052f243439

Sometimes we need to do weird things to the docker container to make the dependencies work properly.

This might fix #210.
