[OGUI-1906] Notification pauses on hover and allows copying

[isaachilly]

I have JIRA issue created

• branch and/or PR name(s) includes JIRA ID
• issue has "Fix version" assigned
• issue "Status" is set to "In review"
• PR labels are selected
• FLP integration tests were ran successful

Ticket:
As a user, I would like to be able to stop notifications from closing when I'm still digesting their information. For example, the JSON parsing errors are long and not easy to read quickly (in 2s before the timeout completes).

The other side of the same coin, being able to copy the message is useful to store it momentarily and would allow user's to quote them in support issues.

Code:
The code adds CSS to support the new design of the notification with a copy button.
Modifies the timeout that ohHover the notification stays.
Change tests to a) allow use of window.notification and then to test the notification model.

Reviewer:
To test the new look the reviewer can edit an instance of a notification.show and go through the different types and test the functionality.

Note

http://localhost:4000/?page=env-overview BKP uses the component in the ENV id dropdown. You will need to temporarily link the WebUI package to the local one. To do this I edited the docker compose file as follows:

# LOCAL ONLY - do not commit. Serves the local WebUi frontend
- type: bind
 read_only: true
 source: ../WebUi/Framework/Frontend
 target: /usr/src/app/node_modules/@aliceo2/web-ui/Frontend

OR if use in a non-dockerised GUI can use npm link.
