Update SSH key missing alert
## Problem to solve

This alert can appear alongside several other alerts simultaneously, and it has been a very long time since this alert has been evaluated.
## Proposal
> Suggestion to consider
Remove global alert and add an info alert section to the `Clone` dropdown and in-line with the buttons on mobile
| Desktop | Mobile |
| ------ | ------ |
|  |  |
## How to make this alert appear
1. Have no SSH key in a GitLab account
2. Visit any project info page
