Add zarf tools yq (or similar) for easily parsing yaml files

[Racer159]

Is your feature request related to a problem? Please describe.

As Ezra I want to be able to use yq with Zarf so that I can quickly pull information out of YAML files / Kubernetes Manifests within actions.

Describe the solution you'd like

• Given I have a manifest I want to pull information from
• When I run zarf tools yq
• Then I have access to the yq CLI: https://github.com/mikefarah/yq

Describe alternatives you've considered

We could explore other libraries but the main yq cli is already written in go - it could also be put behind another layer rather than at the root of tools (to pave the way for potentially more tools like jq)

Additional context

This comes from us wanting to reduce dependencies within Software Factory and open up more options when using UDS Run.

package tools

import (
	yq "github.com/mikefarah/yq/v4/cmd"
)

func init() {
	toolsCmd.AddCommand(yq.New())
}

Successfully embeds yq under zarf tools yq. zarf tools yq --version works properly.

Some things I wasn't able to grok about https://github.com/mikefarah/yq/blob/master/yq.go that may cause issues w/ usage. More research required.

Thanks! I had already gotten that far locally and then sidetracked trying to track down why it made the package so much larger (tldr I wasn't building on Linux). Back to trying to put in doc generation and test things. Will need to try to account for making sure per your note that there aren't issues with certain commands running.
