PowerShell auto-completion [page]deterministic

The kubectl completion script for PowerShell can be generated with the command `kubectl completion powershell`.

To do so in all your shell sessions, add the following line to your `$PROFILE` file:

```powershell kubectl completion powershell | Out-String | Invoke-Expression ```

This command will regenerate the auto-completion script on every PowerShell start up. You can also add the generated script directly to your `$PROFILE` file.

To add the generated script to your `$PROFILE` file, run the following line in your powershell prompt:

```powershell kubectl completion powershell >> $PROFILE ```

After reloading your shell, kubectl autocompletion should be working.
