refactor: Get TS package API response from backend (#168)

* refactor: Get TS package API response from backend

Previously Thunderstore package index was done in frontend. Should be
moved to backend instead as backend is reponsible for such tasks while
frontend should just be used to store and display information.

* refactor: Filter TS API response in backend

* refactor: Rename function

Makes it more descriptive what it does

* refactor: Use gen. binds instead of duped struct

Replaces the current TypeScript interface defintions with autogenerated
bindings.

* fix: Properly type variable

* fix: Correct imported path of interface file

* fix: Update struct field types to fix typing issue

i32 should be big enough unless Thunderstore and Northstar suddenly
becomes really huge and we start seeing over 4 million downloads on some
mod

* fix: Correct imported path of interface file
