Allow Hussein Awala to publish provider docs to S3

[hussein-awala]

Add hussein-awala to the dispatcher allowlist in publish-docs-to-s3.yml.

The workflow gates its build-info job on github.event.sender.login, and every other job
depends on build-info — so when a committer outside the list dispatches it, the run is
created but every job is skipped. There is no error, which makes it easy to mistake for a
successful publish.

Hit while publishing staging docs for the 2026-08-18 provider wave (#71794): the dispatch
returned no error, the run appeared, and all six jobs reported skipped.

Note this does not affect dispatches against an already-cut release tag, since the allowlist
is read from the workflow file at the dispatched ref.

Status	Branch	Result
❌	v3-3-test

You can attempt to backport this manually by running:

cherry_picker 9c8d751 v3-3-test

This should apply the commit to the v3-3-test branch and leave the commit in conflict state marking
the files that need manual conflict resolution.

After you have resolved the conflicts, you can continue the backport process by running:

cherry_picker --continue

If you don't have cherry-picker installed, see the installation guide.
