Add version-file input to read the Helm version from a .tool-versions file (#281 )

+Alternatively, the version can be read from a [`.tool-versions`](https://asdf-vm.com/manage/configuration.html) file (the format used by [asdf](https://asdf-vm.com/) and [mise](https://mise.jdx.dev/)) via the `version-file` input:
+
+```yaml
+- uses: azure/setup-helm@v5.0.0
+  with:
+     version-file: .tool-versions
+  id: install
+```
+
+The action reads the version declared for the `helm` tool, for example:
+
+```
+helm 3.18.4
+```
+
+If both `version` and `version-file` are set, an explicitly requested `version` takes precedence and `version-file` is ignored (a warning is emitted). Because `version` defaults to `latest`, `version-file` is only ignored when you set `version` to a specific value other than `latest`; if `version` is left at its default, the version from `version-file` is used.
+
 > [!NOTE]
-> If something goes wrong with fetching the latest version the action will use the hardcoded default version (currently v3.18.3). If you rely on a certain version higher than the default, you should explicitly use that version instead of latest.

 The cached helm binary path is prepended to the PATH environment variable as well as stored in the helm-path output variable.
