use EUI components for tutorial params (#167014)

## Summary

Partially addresses #46410

Stops using `kuiTextInput` CSS class name in `number_parameter.js` and
`string_paramter.js` components in the `home` plugin.

How to test? I don't know if these parameters are still used, so to test
this apply this patch:

```diff
diff --git a/src/plugins/home/public/application/components/tutorial/instruction_set.js b/src/plugins/home/public/application/components/tutorial/instruction_set.js

+            }}
           />
         </>
       );
```

And go to `/app/home#/tutorial/apm` page, you will see the new parameter
input look there:
