[BUG] Close button appears outside the chrome of the sidebar

[peternied]

Describe the bug
On the collapsibleNav in OpenSearch Dashboards, there is a close button, and the button is floating outside the bounds of the nav. It seems like there is plenty of space to include the button in the nav itself.

To Reproduce
Steps to reproduce the behavior:

1. Start opensearch-dashboards
2. Sign in
3. Look at the side nav menu
   

Expected behavior
The button should be within the bounds of the nav bar

OpenSearch Version

Dashboards Version
v2.0.0, commit :db7cb6d115e

Host/Environment:

• OS: Windows
• Browser and version: Chrome v100

This is intended behavior that is part of folding the latest EUI in. We will revise this in a future update. In the meantime, we should align on using the menuLeft and menuRight icons to open/close the side menu to better align with the correct behavior. For now, the button being outside the container is not unintended behavior.

Yeah I agree! This is expected functionality form EUI. Based on this comment: #1370 (comment) should close this as duplicate for: #569
