[llvm] Revert "workflows: Use main-branch-only environment when using ISSUE_SUBSCRIBER_TOKEN (#179990)" (PR #181352)

[Tom Stellard via llvm-commits]

https://github.com/tstellar created https://github.com/llvm/llvm-project/pull/181352

This reverts commit 31f31dd9d0460834f2ae67247d3886fec4931d6d.

This commit was causing PRs to be spammed with messages like:

"llvmbot temporarily deployed to main-branch-only — with GitHub Actions Inactive"

This was causing confusion, and is not worth the marginal security benefit.  I also think this can be avoided by using called workflows, but I still need to investigate this.
