fix: update dependencies to fix vulnerability

Right now, after the release of the Elastic NPM client version 8.15, they are now using different types. Because this dependency refers to another version, this then breaks and makes it impossible to provide the "client" option when constructing the log sink.

This fixes it, so that it is considered a peer dependency, thus allowing people to use their own version freely.

Should also lead to less maintenance of this package.

@vanthome if you are overburdened, I can help contribute to this project if you set me as repository contributor. I currently maintain a lot of open source projects, and it would be a pleasure to help out with this one too.

@vanthome I also updated relevant other dependencies now. Can we get this out, as it fixes a security vulnerability? We are an enterprise user, so it is necessary for us.
