Merge branch 'create-mr-banner' into 'master'

MR banner & flash notices updates

### What does this MR do?
* Moves the create MR banner below subnav
* Changes MR banner background to white
* Moves flash notices underneath subnav
* Adds container within flash notices to align with content

Closes #22767 
### Why was this MR needed?
It looked a bit out of place between the two navs & had unneeded spacing.
