[llvm] workflows: Fix permissions for release-sources job (PR #100750)

[Tom Stellard via llvm-commits]

https://github.com/tstellar created https://github.com/llvm/llvm-project/pull/100750

For reusable workflows, the called workflow cannot upgrade it's permissions, and since the default permission is none, we need to explicitly declare 'contents: read' when calling the release-sources workflow.

Fixes the error:
The workflow is requesting 'contents: read', but is only allowed 'contents: none'.
