Reusable workflow links ignore `github-enterprise.uri` configuration

**Describe the bug**
When using `github-actions.use-enterprise: true` with a configured `github-enterprise.uri` (e.g. `https://my-company.ghe.com`), the links generated for reusable workflows in the `uses:` clause incorrectly point to `github.com` instead of the Enterprise instance.

**To Reproduce**
Steps to reproduce the behavior:
1. Configure settings:
```json
\"github-enterprise.uri\": \"https://my-company.ghe.com\",
\"github-actions.use-enterprise\": true
```
2. Open a workflow file.
3. Add a reusable workflow reference:
```yaml
uses: my-org/shared-workflows/.github/workflows/workflow.yml@v1
```
4. Hover or Click the link on the `uses` path.

**Expected behavior**
The link should open `https://my-company.ghe.com/my-org/shared-workflows/blob/v1/.github/workflows/workflow.yml`.

**Actual behavior**
The link opens `https://github.com/my-org/shared-workflows/tree/v1/.github/workflows/workflow.yml`.

**Additional Context**
The extension correctly passes `gitHubApiUrl` to the language server `initializationOptions` in `src/workflow/languageServer.ts`, but it appears the link generation logic in the language server defaults to `github.com`

从 src/workflow/languageServer.ts 开始，跟踪 initializationOptions 中的 gitHubApiUrl 如何传递到 reusable-workflow 链接生成流程。启用 github-actions.use-enterprise 后重现悬停或点击行为，然后验证 Enterprise 链接使用配置的主机，而指向 github.com 的链接保持不变。
