[Bug][ColumnMenu] Accessibility issues

[filipKovachev]

Describe the bug
Currently users are not able to open the columnMenu with Tab and open the popup with Enter. It is also not possible to navigate between the checkboxes with tab.

To Reproduce

1. Open this example: https://stackblitz.com/edit/przqark8?file=src%2Fmain.vue
2. Notice how the columnMenu is not opened by pressing Enter and the checkboxes are not navigable via Tab

Expected behavior
The user should be able to open the columnMenu by pressing Enter once the filter icon is focused and the checkboxes must be navigated using tab.
