Import instance: PrismLauncher (Flatpak) path hint is misleading, causes "No instances found"

Please confirm the following.

• I checked the existing issues for duplicate problems
• I have tried resolving the issue using the support portal
• I have ensured my Modrinth App installation is up to date

What version of the Modrinth App are you using?

0.13.15

What operating systems are you seeing the problem on?

Linux

Describe the bug

When trying to import a PrismLauncher instance, the app shows "No importable instances were found at the specified path" even when the path is correct.

Looking at the source code in packages/app-lib/src/api/pack/import/mod.rs, the app expects the PrismLauncher data root folder and then automatically appends the instances subfolder by reading prismlauncher.cfg. If you provide the instances folder directly, it looks for instances/instances/ which doesn't exist.

The UI should hint that you need to provide the launcher data root, not the instances subfolder. Or alternatively, the app should detect both cases and handle them gracefully.
Suggested fix

Add placeholder text in the input field like e.g. /home/user/.local/share/PrismLauncher | /home/user/.var/app/org.prismlauncher.PrismLauncher/data/PrismLauncher Or auto-detect if the user passed the instances subfolder and strip it

Environment

OS: Arch Linux, KDE Plasma Wayland
PrismLauncher: Flatpak (org.prismlauncher.PrismLauncher)
Modrinth App: Flatpak (com.modrinth.ModrinthApp)

and in terminal on Linux (im not sure if this works on another linux)
flatpak override --user
--filesystem=/home/user/.var/app/org.prismlauncher.PrismLauncher \ (change 'user' to your username on your linux)
com.modrinth.ModrinthApp

Steps to reproduce

1.Install PrismLauncher via Flatpak
2.Open Modrinth App → Import instance
3.Paste /home/user/.var/app/org.prismlauncher.PrismLauncher/data/PrismLauncher/instances → fails
4.Paste /home/user/.var/app/org.prismlauncher.PrismLauncher/data/PrismLauncher → works

Expected behavior

No response

Additional context

And Expected behavior:
The UI should show a placeholder hint with the correct path format, and/or auto-detect if the user provided the instances subfolder and handle it gracefully.

This is a good idea! Catalogued internally!
