de30eed14f chore(helm): bump chart version to 0.17.0
The chart lint requires a version bump when chart files change.

3da2a210c7 fix(helm)!: replace dockerize initContainer with bash TCP wait
Drops `apache/superset:dockerize` from the chart entirely. The five
initContainers that gate startup on Postgres / Redis now run from the
same `apache/superset` image we're already pulling, using bash's
built-in `/dev/tcp/host/port` redirect for the readiness probe — no
external `dockerize`, `nc`, or busybox needed.

A trivy scan of the current published `apache/superset:dockerize`
(image created 2024-05-09, alpine 3.19.1 EOSL) found 3 CRITICAL,
25 HIGH, 71 MEDIUM, and 24 LOW CVEs — 64 of them in the bundled
`dockerize` Go binary itself (stale Go stdlib + golang.org/x/{net,
crypto}); the rest in the alpine base. Rebuilding the image on a
fresher base would just defer the same problem; removing the
dependency eliminates it.

Verified `/bin/bash` 5.2.15 is present in `apache/superset:latest`
and supports the `/dev/tcp` redirect (the image's `/bin/sh` is dash,
which does not — hence the explicit `/bin/bash` invocation).
Rendered the chart with `helm template` and confirmed all five
initContainers (supersetNode, init, supersetWorker,
supersetCeleryBeat, supersetCeleryFlower) emit the expected
bash-based probe and pull the main superset image.

The 120s timeout from `dockerize -timeout 120s` is preserved via a
SECONDS-based deadline in the bash loop. Two-port waits (postgres
+ redis) factor out a small `wait_for` helper to keep the script
readable.

BREAKING CHANGE: chart `values.yaml` no longer defines `initImage`.
Operators who customised `.Values.initImage.repository/tag/pullPolicy`
must remove those overrides — they are silently ignored. Operators
who fully overrode `.Values.supersetNode.initContainers` (etc.) are
unaffected; their override still wins. Chart bumped 0.15.5 → 0.16.0.

Closes #40424
