[DO NOT MERGE - POC FOR LAB API] Update Microsoft.Identity.Lab.Api to 0.1.1

[Copilot]

Bumps Microsoft.Identity.Lab.Api to 0.1.1 across the repo and adds it explicitly to the AgentApplicationsTests project.

Changes

• benchmark/Directory.Build.props — MicrosoftIdentityLabApiVersion: 2.0.0 → 0.1.1
• tests/Directory.Build.props — MicrosoftIdentityLabApiVersion: 2.0.0 → 0.1.1
• tests/E2E Tests/AgentApplications/AgentApplicationsTests.csproj — added direct package reference:

  <PackageReference Include="Microsoft.Identity.Lab.Api" Version="0.1.1" />

Microsoft.NET.Test.Sdk versions are unchanged.

Original prompt

Create a new pull request to update Microsoft.Identity.Lab.Api to version 0.1.1 with the following requirements:

1. Set MicrosoftIdentityLabApiVersion to 0.1.1 in all Directory.Build.props files that define this property (in benchmark/ and tests/ directories)
2. Add <PackageReference Include="Microsoft.Identity.Lab.Api" Version="0.1.1" /> to tests/E2E Tests/AgentApplications/AgentApplicationsTests.csproj
3. Do NOT update any Microsoft.NET.Test.Sdk versions - keep them as they are currently defined

This is similar to PR #3754, but with different version requirements.
