URL parameters could be used to modify the root prototype, eg.:
?__proto__.toString=peter
Fortunately, the assigned value is always a string, so it's not possible
to overwrite functions with other functions. The example above just
leads to a JS error which is caught by the application and an error is
then displayed. It might be possible to add a new field to the prototype
that then leads to other code checking `if ('foo' in obj)` to behave
differently. But I couldn't find a spot that could be abused. I might
very well have missed something, but my guess would be that this
vulnerability is not really exploitable in a bad way.
Note: I think only one of the `{}` needs to be replaced by
`Object.create(null)`, but it doesn't hurt just replacing all of them.
From a quick glance, I also didn't find any similar problems in the
code base.
This updates a ton of other dependencies. In particular, it also fixes a ton of security issues within the dependency tree.

PR is mainly for the first commit which fixes a prototype pollution issue in Studio. As the commit message says, we couldn't find a way to actually exploit it, so we don't think this is a high impact security issue. It's scary though, so it needs to be fixed for sure. We only found ways to break Studio (but that's not particularly useful to an attacker): https://studio.opencast.org/?__proto__.toString=peter
The other commits are about updating dependencies to get rid of security issues in those.
