Fixes #53296
As per the linked issue, this PR sets top-level read-only permissions on all workflows. This reduces risks in case any workflow dependencies are compromised in a supply-chain attack.
Some of the workflows seem to require
contents: write
permissions to push directly to the repository. These have been given read-only top-level permissions and then write permissions at the job level. This is for future proofing, in case additional jobs that do not require write access are added to the workflow.
