Resolve gradle user home misconfiguration

[aaronrebak]

Resolves issue: #20928

Traditionally happens against a CI pipeline with a custom gradle user home.

The issue occurs when extensions such as quarkus-jacoco attempt to load an ApplicationModel and the project being used:

• Contains a custom gradle user home that is not ~./gradle
• The custom gradle user home contains custom gradle.properties (traditionally something like repoUsername and repoPassword) in order to resolve dependencies from a private repository.

As a result of the custom gradle.properties file missed, the user is presented with errors related to missing gradle properties or not being able to resolve dependencies.
