feat: Enable setting schedulerName in Helm chart

[robinkb]

Fixes #7455

Description

Enables setting schedulerName on the Karpenter to pod to support specifying a custom scheduler.

How was this change tested?

$ helm template charts/karpenter --show-only templates/deployment.yaml
# Verified that the template contains `schedulerName: "default-scheduler"`
$ template charts/karpenter --show-only templates/deployment.yaml --set schedulerName=fargate-scheduler
# Verified that the template contains `schedulerName: "fargate-scheduler"`

Does this change impact docs?

• Yes, PR includes docs updates
• Yes, issue opened: #
• No

It kinda does impact documentation, namely the Helm chart README. But it appears that the Helm chart README is not up-to-date, as running helm-docs includes changes that are not caused by my PR.
