[image] re-add gtk3 package dependencies (#186)

A side effect of earlier commit b280f37 is that gtk3 weak dependencies
were no longer installed while building the RapiDAST image.

As a result, firefox would refuses to start.

This commit re-add gtk3 dependency installation.

If we need to reduce the image size, we would probably need to select
which dependencies to install, one by one (there are a lot, though)
