ci: build linux arm64 prebuilds

[zy6p]

Problem

nodejieba publishes prebuilt binaries via node-pre-gyp, but GitHub Releases currently only contain linux-x64-glibc artifacts. On Linux arm64, install falls back to source build (or hits 404) because the release assets are missing.

Example install log (Linux arm64):

node-pre-gyp http GET https://github.com/yanyiwu/nodejieba/releases/download/v3.5.5/nodejieba-v3.5.5-node-v115-linux-arm64-glibc.tar.gz
node-pre-gyp ERR! install response status 404 Not Found

Fix

• Add ubuntu-22.04-arm to the CI matrix for both test.yml and github_release.yml
• Install basic build deps on Linux runners
• (Release workflow) add a workflow_dispatch input tag so maintainers can backfill missing assets for an existing tag (e.g. v3.5.5)

After this, GitHub Releases will include e.g. nodejieba-v{version}-{node_abi}-linux-arm64-glibc.tar.gz alongside existing x64 artifacts.

Notes

This keeps the existing packaging flow (node-pre-gyp package + softprops/action-gh-release).
