Top anchor modification

Hi,

The top anchor is allways redirecting to the main page / top page of a TYPO3 installation.

I would suggest to adapt ScrollTop.html as follows (including the page link):

```

```
Like that, you get a smooth scroll to the current page.

Best regards and thank you for your great work!

Start by locating the ScrollTop.html template and inspecting how its current top anchor links to the main page. Update the scroll-top link to target the current page's top section as proposed, then verify that activating it scrolls smoothly to the top of the current TYPO3 page.
