Feature Request: Add semver range support to allow installing Helm v3.x or any major/minor version

### Feature request

Currently, the action allows only fully pinned versions like:
```
with:
version: v3.19.2
```
It would be helpful to support semver ranges such as:
* `v3.x` : latest Helm v3 patch
* `v3.19.x`: latest Helm v3.19 patch

This makes it easier to stay on a major or minor version without hardcoding every single release. It also avoids accidental upgrades to Helm v4.

It's generally a good practice to be able to set the semver range. Please consider adding this functionality.
