Can we add a testcase here for this functionality as well?

### Proposed changes
<!--Give us a brief description of what you've done and what it solves.
-->
This PR stabilizes Helm upgrades **by abandoning the use of checksums**
(which was added in v4.5.0, see
[PR](#2568)), while
allowing for local chart change detection via the chart's version
number. That is, the user would be expected to touch the chart's version
to compel Pulumi to roll out the change.
Implementation-wise, this is accomplished by resolving the `version`
property during `Check`. The checked input reflects the goal version,
and if the goal has changed, then `Diff` detects this in the natural way
and effects an upgrade. `Check` no longer uses `helm template` to render
the chart, it simply resolves the chart version.
The diff logic is improved here to use a three-way merge, to be able to
detect drift in the actual Helm release.
The refresh logic is improved to not mutate inputs (as was done in the
past to help with drift detection).

Proposed changes
This PR fixes a usability problem with the
kubernetes:helm.sh/v3:Releaseresource when using a local chart. With this fix, Pulumi automatically detects changes to the rendered output of the chart and performs a Helm upgrade accordingly. It does this by persisting a SHA256 checksum of the chart output into the Pulumi stack state.Users may suppress change detection with the
ignoreChangesoption, i.e.ignoreChanges: ["checksum"].Upgrade considerations: after upgrading the provider, users should expect to see a diff (
checksumproperty) and a corresponding Helm upgrade. Helm upgrades are generally idempotent.Related issues (optional)
