Add emoji to GitHub Actions step names for consistency

Several workflows were missing the emoji-prefixed step naming used
elsewhere (e.g. nightly-build.yml, build-submit-ios/android.yml), and
a couple of files that already used emoji had a few gaps. Fills those
in across all workflow files. Job-level `name:` fields are left
untouched since some are pinned as required branch-protection check
names.
