Jon Ross-Perkins b73387fc84 Update workflows for security hardening. (#4192)
Also a small pass on workflow names.

Note, I'm a little concerned that the test/nightly release/pre-commit
endpoints may be fragile. At the same time, it's also where it may be
most useful, to prevent network access by arbitrary test code. I think
this is imperfect, but maybe we can try it out and see if it's much of
an issue.

Note, the discord wiki action is currently broken, this should fix it.

Workflows

Hardening

Workflows are hardened using Step Security tool. Findings for the "Harden Runner" steps are available online.

Allowed endpoints

Most jobs only have a few endpoints, but due to tools which do downloads, a few have significantly more. These are:

  • pre_commit.yaml (Bazel, pre-commit)
  • nightly_release.yaml (Bazel)
  • tests.yaml (Bazel)

When updating one of these, consider updating all of them.

We try to keep allowed-endpoints with one per line. Prettier wants to wrap them, which we fix this with prettier-ignore.

Testing

We keep around an action-test branch in carbon-lang, which can be used to test triggers with push: configurations. For example:

on:
  push:
    branches: [action-test]
