Migrate lab IDE to use mise

[niallthomson]

What would you like to be added?

Currently the lab IDE installs binaries using a shell script:

https://github.com/aws-samples/eks-workshop-v2/blob/main/lab/scripts/installer.sh

This should be migrated to use to use mise to install these binaries instead.

Renovate has support for mise so we should continue to get automated dependency updates

Implementation

Create a mise.toml file under lab that expresses all our dependencies.

Why is this needed?

Removes our custom shell script and the custom renovate integration based on regex
