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

[Krad-dono]

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:

   \"github-enterprise.uri\": \"https://my-company.ghe.com\",
   \"github-actions.use-enterprise\": true

2. Open a workflow file.
3. Add a reusable workflow reference:

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
