small BugReport - modify path for links in advanced preferences documentation

LenaMK

Hi,

I just noticed two path errors in Documentation > Preferences > advanced # shortcuts (https://www.zotero.org/support/preferences/advanced#shortcuts).

Current links to `quick search`and `feed` lead to :
> This topic does not exist yet
> You've followed a link to a topic that doesn't exist yet. If permissions allow, you may create it by clicking on “Create this page”.

I removed "/preferences" to find the contents.

Quick Search
- current: https://www.zotero.org/support/preferences/searching
- correction: https://www.zotero.org/support/searching

feed
- current: https://www.zotero.org/support/preferences/feeds
- correction: https://www.zotero.org/support/feeds

Created a wiki account to update them myself but realised I don't have access.
Cheers
