Change tooltip of override icon in result details

[saberlynx]

What:

Change tooltip of override icon in result details.

Why:

Currently, the tooltip is "Overrides are applied.". This shows even on the result details, but that is misleading because we do not apply the new severity etc. on the result detailspage.

How:

Manual testing in web app.

Checklist:

• Tests
• CHANGELOG Entry
