fix(ci): replace fake action SHA pins in e2e.yml template stubs (#30)

This file inherits its e2e.yml from the rsr-template-repo template, which
carried 4 fabricated action SHA pins in template-comment stubs. The pins
were inert in commented form here, but would have 422'd at action
resolution if anyone uncommented them. Caught and fixed at the template
source in hyperpolymath/rsr-template-repo#81 (merged); this PR sweeps
the propagated stubs.

  goto-bus-stop/setup-zig  7ab2955...3608  -> abea47f...39406  (v2.2.1)
  erlef/setup-beam         5a67e1a...a66c07 -> fc68ffb...db2f93 (v1.24.0)
  denoland/setup-deno      5fae568...c3497 -> 667a34c...c7282  (v2.0.4)
  haskell-actions/setup    dd344bc...3a40fce -> cd0d9bd...e0553 (v2.11.0)

All four real SHAs verified via `gh api repos/<org>/<action>/commits/<sha>`.

Originally discovered while wiring CI for hyperpolymath/snifs#30.
