Installation instructions refer to non-existent file

[langston-barrett]

The installation instructions refer to https://github.com/rems-project/cerberus/blob/master/backend/cn/README.md, which does not exist.

These URLs should be fixed:

cn-tutorial/docs/getting-started/installation.md

Line 3 in a428c31

To fetch and install CN, visit the [Cerberus repository](https://github.com/rems-project/cerberus) and follow the instructions in [backend/cn/README.md](https://github.com/rems-project/cerberus/blob/master/backend/cn/README.md).

cn-tutorial/src/tutorial.md

Line 24 in a428c31

To fetch and install CN, visit the [Cerberus repository](https://github.com/rems-project/cerberus) and follow the instructions in [backend/cn/README.md](https://github.com/rems-project/cerberus/blob/master/backend/cn/README.md).

It appears that this file was removed in rems-project/cerberus#944. This would likely be a good new target: https://github.com/rems-project/cn?tab=readme-ov-file#installation

Seems to be fixed (at least in the testing-tutorial branch). Message ID: ***@***.***>

@bcpierce00 that seems to work!

I found however another outdated link - in https://rems-project.github.io/cn-tutorial/getting-started/tutorials/welcome/#setup-instructions there is a link to the zipped exercises, currently it links to link:exercises.zip which is incorrect.

Looks like both the URL and the file itself needs to be updated (assuming it hasn't been done yet).
