Fix DbGate Redis connectivity by using TLS Redis URLs

[Copilot]

DbGate could not connect to Redis in newer Aspire/Redis combinations because the Redis connection URL generated by WithDbGate() used a non-TLS scheme, while Redis expected TLS. This updates the generated URL format to align with current Redis defaults used in the integration.

• Redis DbGate URL generation

  • Updated Redis URL construction in RedisBuilderExtensions.WithDbGate() from redis:// to rediss://.
  • Applies to both password and non-password URL forms.

• Test expectation alignment

  • Updated Redis URL assertions in:
    • CommunityToolkit.Aspire.Hosting.Redis.Extensions.Tests/ResourceCreationTests
    • CommunityToolkit.Aspire.Hosting.DbGate.Tests/AddDbGateTests
  • Expected DbGate env vars now assert rediss://... for Redis connections.

• Behavioral effect

  • DbGate now receives Redis connection definitions that match TLS-enabled Redis endpoints, avoiding protocol mismatch timeouts.

var redisUrl = redisResource.PasswordParameter is not null
    ? ReferenceExpression.Create($"rediss://:{redisResource.PasswordParameter}@{name}:{redisResource.PrimaryEndpoint.TargetPort}")
    : ReferenceExpression.Create($"rediss://{name}:{redisResource.PrimaryEndpoint.TargetPort}");

Looks like the build failed due to MessagePack version 2.5.192 referenced via Microsoft.SqlServer.DacFx in the SqlDatabaseProjects has moderate severity vulnerability. The project already suppresses NU1903 (high severity) but not NU1902 (moderate severity). Suggesting to add NU1902. However the real fix is probably to wait for Microsoft.SqlServer.DacFx to ship an update that bumps MessagePack to a non-vulnerable version.

Pull request overview

This PR updates the Redis → DbGate connection URL generated by RedisBuilderExtensions.WithDbGate() to use the TLS Redis scheme (rediss://) so DbGate can connect to TLS-enabled Redis endpoints in newer Aspire/Redis combinations.

Changes:

• Updated Redis DbGate URL generation from redis:// to rediss:// (password and non-password forms).
• Updated unit test expectations to assert rediss://... for the Redis DbGate URL env var.
