A function that can import "options.txt" file from the other modpack when creating a modpack

[AquaticZzzz]

Currently, when setting up a new modpack, I have to manually copy the options.txt file (and potentially other configuration files, hotbar.nbt etc.) from an existing instance to keep my custom keybinds, video settings, and accessibility options consistent. It is a repetitive process when creating multiple instances.

While the current "Copy Instance" feature allows carrying over these settings, it creates a full clone of the instance, including all mods and data. A more lightweight "Import settings" option would be very useful when setting up fresh or experimental instances, allowing us to quickly apply preferred keybinds and video settings without creating a heavy duplicate.

This would be a significant quality-of-life improvement for users who maintain multiple instances and want to keep their settings consistent across them.
It may be the same as #5312, #774 and #1077
I'm sorry if anything is unclear, as English is not my first language.
