chore: move pnpm-related config to pnpm-workspace.yaml (#65)

Move pnpm-related configurations from `.npmrc` to `pnpm-workspace.yaml`.

This would resolve the warning during publishing:

```
. prepare: npm warn Unknown env config "verify-deps-before-run". This will stop working in the next major version of npm.
. prepare: npm warn Unknown env config "strict-peer-dependencies". This will stop working in the next major version of npm.
. prepare: npm warn Unknown env config "_jsr-registry". This will stop working in the next major version of npm.
. prepare: npm warn Unknown env config "hoist-workspace-packages". This will stop working in the next major version of npm.
. prepare: npm warn Unknown project config "public-hoist-pattern". This will stop working in the next major version of npm.
. prepare: npm warn Unknown project config "hoist-workspace-packages". This will stop working in the next major version of npm.
. prepare: npm warn Unknown project config "strict-peer-dependencies". This will stop working in the next major version of npm.
```

Also, integrate with https://github.com/pnpm/plugin-better-defaults.
