Custom Cluster Registration for rke2 windows nodes formats taints, labels incorrectly for powershell

[slickwarren]

Setup

• Rancher version: v2.7.6
• Rancher UI Extensions: n/a
• Browser type & version: chrome (any)

Describe the bug

the windows node registration command isn't properly adding Labels and/or Taints are not formatted correctly. Windows is requesting that they have 1 flag per request, but we currently add a new - Label '<label=value>' per label instead of what windows is asking for, - Label '<label1=value1,label2=value2,...>'

To Reproduce

create a custom rke2 cluster register a windows node with 1 label and 2 taints

Result windows node fails to register with generated registration command from rancher

Expected Result

resulting registration command should work with windows.

provide multiple values to parameters that can accept multiple values, use the array syntax. For example, "-parameter
