Fix Uninstall-PSResource blocking uninstall of a dependency version when a newer version satisfies a minimum-version requirement

[Copilot]

Uninstall-PSResource refuses to uninstall a package version if any installed module lists it as a dependency — but the check only compares the literal version number recorded in RequiredModules, without distinguishing an exact RequiredVersion from a minimum ModuleVersion/MaximumVersion range. As a result, uninstalling a version that satisfies a minimum-version dependency fails even when a newer installed version of the same package would still satisfy that dependency.

Root cause

• CheckIfDependency in UninstallPSResource.cs treats any match between the version being uninstalled and the version recorded on the resolved RequiredModules entry as blocking, regardless of whether the requirement is a minimum version or an exact version.

Changes

• Read the dependent module's raw manifest RequiredModules entry (via Import-PowerShellDataFile) to determine whether the requirement is an exact RequiredVersion or a range (ModuleVersion/MaximumVersion).
• For range requirements, only block the uninstall if no other installed version of the package also satisfies the range. Exact RequiredVersion requirements keep the original blocking behavior.
• Added IsAnotherInstalledVersionSatisfyingRequirement / GetRawRequiredModuleEntry helpers to encapsulate this logic.

Tests

• Extended New-TestModule test helper with an optional -requiredModulesEntry parameter to author custom RequiredModules content.
• Added Pester tests (local file-based repository, no external network dependency) covering:
  • Uninstalling a version that satisfies a minimum-version dependency succeeds when a newer installed version also satisfies it.
  • Uninstalling is still blocked when no other installed version satisfies the minimum-version requirement.

Example

# dbatools requires dbatools.library >= 2025.11.29.0 (ModuleVersion, not RequiredVersion)
# Both 2025.11.29 and 2025.12.4 of dbatools.library are installed
Uninstall-PSResource -Name dbatools.library -Version 2025.11.29
# Previously: blocked with "This package is a dependency for: 'dbatools, dbatools'"
# Now: succeeds, since 2025.12.4 still satisfies the minimum-version requirement
