Fix deriveChartTag to support semver wildcard patterns

[gusevda]

What does this PR do?

deriveChartTag now handles Masterminds/semver wildcard placeholders (x, X, *) by normalizing them to 0. Previously, inputs like 1.2.x or 1.x returned undefined, which disabled the Edit Deployment button with "missing chart version".

What is the effect of this change to users?

Deployments using wildcard semver constraints (e.g. 1.2.x, 1.*.*) can now be edited via the Edit Deployment button.

Any background context you can provide?

deriveAutoUpgradeMode already handles wildcards correctly. Only deriveChartTag needed updating — its regex required all three version components to be digits.

Examples of the new behavior:

• 1.2.x → 1.2.0 (patch wildcard)
• 1.x / 1.*.* → 1.0.0 (minor wildcard)
• ~1.2.x → 1.2.0 (operator + wildcard)
• * / x.x.x → 0.0.0 (full wildcard)

Do the docs need to be updated?

No.

Should this change be mentioned in the release notes?
