Fix emacs native compilation warning

Fix emacs native compilation warning

```
 ■  Warning (comp): use-package-core.el:907:2: Warning: docstring has
wrong usage of unescaped single quotes (use \= or different quoting)
 ■  Warning (comp): use-package-core.el:930:2: Warning: docstring has
wrong usage of unescaped single quotes (use \= or different quoting)
```

To reproduce, have emacs build with native compilation and notice the
compilation logs. You can then open this file and run `M-x
emacs-lisp-native-compile-and-load` before and after the changes to see the
warning is removed.
