Issue with Views Sticky Headers with Core 10.3

Problem/Motivation

After updating core to 10.3 and above, the Enable Drupal style "sticky" table headers views option no longer works in this theme or themes which depend on this theme.

Steps to reproduce

1. Update to Drupal 10.3 or later
2. Create a view with a table display
3. Check the Enable Drupal style "sticky" table headers option

Proposed resolution

Drupal core issue 3439580 changed usage of the .sticky-enabled css class to now be .sticky-header

We should update the css classes used in views-view-table.html.twig to include both CSS classes for backwards and forwards compatibility.
