[llvm] workflows/release-binaries: Always pull composite actions from main branch (PR #100805)

[Tom Stellard via llvm-commits]

https://github.com/tstellar created https://github.com/llvm/llvm-project/pull/100805

If we pull from the release tag, then if there is a bug in one of the actions on the release tag, then we can never do a build for that tag. Pulling from main will allows us to fix bugs in the actions we use to build the releases.
