fix(federatedfilesharing): pre must not be a child of p

Fix the problem reported:

> [plugin vite:vue] apps/federatedfilesharing/src/components/PersonalSettings.vue: <pre> cannot be child of <p>, according to HTML specifications.

> This can cause hydration errors or potentially disrupt future functionality.

`p` only allows inline elements, but pre is none.

We either need to use `div` instead of `p` or `code` instead of `pre`.

But in this case we want a block of code, so we use `div` and inner

`<pre><code>`.
