feat: add confirm dialog for installing mods

When selecting multiple mods at once, it can become hard to keep track
of which ones you selected.

To address this, a dialog is now displayed
when you finish selecting the mods to download, showing you which ones
you selected and their filenames. From there, you can either accept it
and download the mods, or you can cancel it and go back to the mod
selection dialog.
