Fix ModsTableTooltip Component

[otobot1]

Is your feature request related to a problem? Please describe.
We are currently using Mantine's floating tooltips (<Tooltip.Floating>), which are ignored by screen readers and also don't let the user select the text in the tooltip.

Describe the solution you'd like
Use Mantine's static tooltips instead (<Tooltip>). In this case, we need to get the multiline functionality working and make onMouseEnter and onMouseLeave work for the component in the dropdown.

Describe alternatives you've considered
Use the Mantine Popover component instead (like in the ModDownloadButton component) and simply style it to look like the static Tooltip (this might be simpler).

Follow-up to #752 issue 2.
