Incorrect version reference in documentation for azure/trusted-signing-action

[teamchong]

Description:
The current documentation/example references azure/trusted-signing-action@v0.4.1, which does not exist. The latest available version is v0.4.0. This causes errors when attempting to use the action as shown in the example.

Steps to Reproduce:

1. Set up a GitHub Actions workflow using azure/trusted-signing-action@v0.4.1 as specified in the documentation.
2. Attempt to run the workflow.
3. Observe the error indicating that v0.4.1 cannot be found.

Expected Behavior:
The workflow should reference an existing version of the action, allowing it to run without errors.

Actual Behavior:
The workflow fails with an error message: Unable to resolve action azure/trusted-signing-action@v0.4.1, unable to find version v0.4.1.

Suggested Fix:
Update the documentation to reference the correct version azure/trusted-signing-action@v0.4.0.

Additional Context:
This issue can cause confusion for users trying to set up the action for the first time. Updating the documentation would improve user experience and prevent similar errors in the future.
