Update API baseline for NetworkEndpointSnapshotList changes

[Copilot]

Description

Addresses feedback from #14459 to update the public API baseline file (src/Aspire.Hosting/api/Aspire.Hosting.cs) to reflect changes made to NetworkEndpointSnapshotList.

Changes

• Added AddOrUpdateAllocatedEndpoint(NetworkIdentifier, AllocatedEndpoint) to API baseline
• Added GetAllocatedEndpointAsync(NetworkIdentifier, CancellationToken) to API baseline
• Marked TryAdd(NetworkIdentifier, ValueSnapshot<AllocatedEndpoint>) with [System.Obsolete] attribute in API baseline
• Fixed XML documentation typo in AddOrUpdateAllocatedEndpoint ("Adds and" → "Adds or updates an")

This ensures API analyzers stay in sync with the actual public API surface changes.
