Add Microsoft.Build.Tasks.Core dependency management via Version.Details.xml

[Copilot]

MSBuild dependency version is currently hardcoded in Directory.Packages.props and requires manual updates. This PR adds centralized version management for the MSBuild package via darc automation.

Changes

• eng/Version.Details.xml: Added Microsoft.Build.Tasks.Core dependency under ProductDependencies
• eng/Version.Details.props: Added MicrosoftBuildTasksCoreVersion property for darc to manage
• Directory.Packages.props: Updated to use $(MicrosoftBuildTasksCoreVersion) property directly in the PackageVersion entry and removed the redundant override

Note: The property is defined in Version.Details.props where darc will automatically update it during dependency flows from the appropriate MSBuild repository.

<issue_title>Automate the updates of MSBuild dependencies</issue_title>
<issue_description>Currently, MSBuild dependency needs to be updated manually by revving the version specified here:

deployment-tools/Directory.Packages.props

Line 12 in 84ccc05

<PackageVersion Include="Microsoft.Build.Tasks.Core" Version="17.10.29" />

Consider implementing an automated process. Perhaps darc subscription can be utilized.</issue_description>

@copilot please update Directory.Packages.props to utilize the new property in the explicit PackageVersion entry for this package -

deployment-tools/Directory.Packages.props

Line 12 in 84ccc05

<PackageVersion Include="Microsoft.Build.Tasks.Core" Version="17.10.29" />

@copilot please update Directory.Packages.props to utilize the new property in the explicit PackageVersion entry for this package - https://github.com/dotnet/deployment-tools/blob/84ccc0553245e903...

Done in 3356b83. Updated line 12 to use $(MicrosoftBuildTasksCoreVersion) directly and removed the now-redundant override entry.

[NikolaMilosavljevic]

Closing as we do not want to flow this package updates from VMR. Will create a new PR with correct flow from the appropriate MSBuild repo.

@copilot move the new property from Version.Details.props to Versions.props

@copilot move the new property from Version.Details.props to Versions.props

Done in e4837c4. Moved the MicrosoftBuildTasksCoreVersion property from Version.Details.props to Versions.props.

Given this is a darc/Version.Details.xml dependency, this property should be defined in Version.Details.props. This is relatively new. This is where all darc will define/update the property on dependency flows.

[NikolaMilosavljevic]

Oh, I see - I thought that those are for VMR flow only.

[NikolaMilosavljevic]

@copilot move the new property back to eng/Version.Details.props file.

Done in 80252f3. Moved the MicrosoftBuildTasksCoreVersion property back to Version.Details.props where darc will manage it.
