Fix circular dependency in uikit/tableheader library

Problem/Motivation

Fatal error allowed memory size в LibraryDiscovery.php on line 58 when opening any page with table.

Steps to reproduce

Install uikit_admin and set it as Administration theme, then go to any page with table.

Proposed resolution

I think the correct solution is to replace `uikit/tableheader` with `uikit/uikit` in `uikit_admin.libraries.yml`

diff --git a/uikit_admin.libraries.yml b/uikit_admin.libraries.yml
