org-cliplink does not always use the system clipboard

### What did you expect to happen?

I have set
```elisp
(setq select-enable-clipboard nil)
```
to make doom behave more like vim (syncing the system clipboard to kill is really annoying to me).

The documentation for `org-cliplink` states that it uses the system clipboard, so I expect it to still insert the system clipboard content.

### What actually happened?

Using `org-cliplink`, the kill content gets inserted instead of the system clipboard.

### Describe your attempts to resolve the issue

I have looked into `org-cliplink`:
```
(defcustom org-cliplink-simpleclip-source nil
"Clipboard source.
Non-nil means use system clipboard as source.
The clipboard content will be provided by `simpleclip',
requiring simpleclip.el to be installed.
```
This is set to `nil` in doom and simpleclip.el doesn't seem to be installed by default.

### Steps to reproduce

1. set
```elisp
(setq select-enable-clipboard nil)
```
2. open an org file
3. put an URL into the system clipboard
4. delete some text in the document with `dd` (to fill the kill ring)
5. invoke `M-x org-cliplink`
