Give token write permissions for gh release create

[verhovsky]

Currently the publish workflow fails with

  gh release create "$GITHUB_REF_NAME" --generate-notes dist/*
  shell: /usr/bin/bash -e {0}
  env:
    NPM_CONFIG_USERCONFIG: /home/runner/work/_temp/.npmrc
    NODE_AUTH_TOKEN: XXXXX-XXXXX-XXXXX-XXXXX
    GH_TOKEN: ***
HTTP 403: Resource not accessible by integration (https://api.github.com/repos/tree-sitter/node-tree-sitter/releases)
Error: Process completed with exit code 1.

This is an LLM suggestion (Codex with gpt-5.5 xhigh)

Seems like it's worth a shot, thoughts @ObserverOfTime?
