Issue Description

The behavior is as follows, in brief.
Given a object parameter, say pythonVersions, made by key (name) values (py ver):

• ✅ if parsed in azure-pipeline file: "3.10" returns "3.10"
• ❌ if parsed in a template "3.10" always returns "3.1"
• ✅ if parsed in a template "3.11" returns "3.11"

It appears to be a bug in object parsing between pipeline and templates, particularly the zero of the decimal ten.

Here a repository to fully reproduce the issue is provided

Hi @gianfaProm
Could you please share the task which you are using in the pipeline?

[gianfaProm]

Hi @v-schhabra , thanks for the reply,
I am using UsePythonVersion@0.
I also shared a .zip from which to reproduce the behavior, if that helps.

In any case at first glance it would seem to be more of an object passing problem between pipeline and template, rather than a usePythonVersion problem, but maybe I'm wrong
