Migrate lab IDE to use mise

### 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](https://mise.jdx.dev/) to install these binaries instead.

Renovate has [support](https://docs.renovatebot.com/modules/manager/mise/#backends-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

Start with lab/scripts/installer.sh and inventory the binaries it installs, then inspect the lab Renovate configuration for the custom regex integration. Create lab/mise.toml expressing those dependencies, migrate the lab IDE setup to use it, and verify that the custom installer and Renovate integration are no longer needed.
