[SDK] Typescript aliases in import paths are not resolved after compilation

[ilyamore88]

Description

SDK package uses @/ alias for src folder:

    "paths": {
      "@/*": ["./src/*"]
    }

Typescript compilation doesn't replace this alias in imports paths. See https://www.typescriptlang.org/tsconfig/#paths

Note that this feature does not change how import paths are emitted by tsc, so paths should only be used to inform TypeScript that another tool has this mapping and will use it at runtime or when bundling.

Problems caused

ts-jest library uses compiled version of sdk from dist folder. When I run tests on core package, it can't resolve path to type and fails with Typescript error. Example: https://github.com/editor-js/document-model/actions/runs/29044585271/job/86209971879

      Property 'prepare' does not exist on type 'BlockToolConstructor<any, any, any>'.

       if (isFunction(toolConstructor.prepare)) {
                                             ~~~~~~~

                                          ~~~~~~~

Possible solutions

1. Remove alias from core package
2. Use library like tsc-alias after compilation
