ci(*): update helm-chart-smoketest.yml, add wasmtime-v1 coverage

[vdice]

Describe your changes

• Updates the helm chart smoke test to support more than the spin shim
• Add coverage for the wasmtime-v1 shim/app

Notes:

• This effort has (re-)churned up issue(s) with the k3d distro (before, we would skip a few checks that glossed over the behavior); for now, in this PR, I've just included a generous timeout, but a follow-up is needed to determine why it can sometimes take many failed shim install pods before the shim is ready. (For instance, the other distros usually finish in ~1.5-3 minutes, whereas the k3d variant can be in that range but can also, mysteriously, take much longer)
  • I'm cautiously optimistic that shim-downloder: retry logic #591 may help
• I realize this shell-based approach is probably nearing the limits of maintainability/readability. Happy to brainstorm follow-up(s) on how to improve or migrate to a different test harness. (Could be as simple as moving inline bash into scripts to improve the workflow 'flow' itself)

Depends on #604 (Can rebase after that lands)

Closes #602

@kate-goldenring this should be ready for a re-review. I am still seeing instability with the k3d flavor of the smoketest (passing sometimes, timing out other times); if it continues to plague us, we can deactivate it while digging deeper. I did disable setting the containerdRuntimeOptions for this distro, but it doesn't seem to help this particular behavior.

Note that this PR does rely on the following fix (specifically for the wasmtime shim): #604
