* Part 2 of eslint prefer-const

* Release notes

* Update

Co-authored-by: kyrias <johannes@kyriasis.com>

- Enforce that imports from the same package are merged into a single
import
- In `loot-core`, require that imports of other `loot-core` files use a
relative import (like the vast majority of such imports) rather than
specifiers starting with `loot-core/` (probably a result of moving files
out of other packages into `loot-core`)

Another batch of `loot-core` migrated.
