FR: Print brew upgrade instructions when kurtosis cli users are using an outdated version of kurtosis cli

[leeederek]

Background & motivation

Kurtosis releases updates quite often. This is awesome, but this also means users will likely be using out-of-date versions of Kurtosis.

Currently the WARN looks like this:

WARN[2023-08-18T12:14:39+01:00] You are running an old version of the Kurtosis CLI; we suggest you to update it to the latest version, '0.81.9'
WARN[2023-08-18T12:14:39+01:00] You can manually upgrade the CLI tool following these instructions: https://docs.kurtosis.com/install#upgrading

Desired behaviour

When I am using an outdated version of Kurtosis CLI, I would like the terminal to print the following:

WARN[2023-08-18T12:14:39+01:00] You are running an old version of the Kurtosis CLI; we suggest you to update it to the latest version, '0.81.9'
WARN[2023-08-18T12:14:39+01:00] Upgrade using: brew update && brew upgrade kurtosis-tech/tap/kurtosis-cli && kurtosis engine restart. For other ways to upgrade, visit: https://docs.kurtosis.com/install#upgrading

How important is this to you?

Nice to have; this feature would make using Kurtosis more enjoyable.

One step better would be a WARN line that reads

WARN[2023-08-18T12:14:39+01:00] You are running an old version of the Kurtosis CLI. 

Would you like to upgrade the Kurtosis CLI? (Y/N):

@leeederek Derek agreed, and this message has bugged me for a little while. Unfortunately, Homebrew isn't the only way users install our CLI. What about this?

WARN[2023-08-18T12:14:39+01:00] You are running an old version of the Kurtosis CLI. To update to the latest (0.81.9), run the following:
     <print specific version information; e.g. `brew update && brew install kurtosis-tech/tap/kurtosis-cli`>
     kurtosis engine restart
