Fix interaction_ts import path in package.json (currently hardcoded to local node/ path)

[wulfraem]

The current import path for interaction_ts in the package.json in bindings/wasm/wasm_identity is hardcoded to the local node/ path.

Instead, we should be pointing to this dependency with a more flexible import, that supports node and web builds.

Unit tests for node WASM builds were running into issue due to being unable to find the @iota/iota-interaction-ts/move_calls/identity dependency as well, which sounds like it's related to this issue, e.g.:

Run npm run test:unit:node
  npm run test:unit:node
  shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}
  env:
    SCCACHE_DIR: /home/runner/.cache/sccache
    RUSTC_WRAPPER: sccache
    CURRENT_DATE: 2025-02-19

> @iota/identity-wasm@1.4.0 test:unit:node
> ts-mocha -p tsconfig.node.json ./tests/*.ts --parallel --exit
