chore: Update dotnet monorepo

Now that #1911 is merged, all `Execute` methods of commands have a new CancellationToken parameter. Update the documentation to reflect that.

New documentation shall still be written with an example on how to pass the top-level CancellationToken to the app.Run(Async) method.

+Title: Spectre.Console 0.52.0 released!
+Description: Don't eat (too much) glue.
+Published: 2025-10-10
+Category: Release Notes
+Excluded: false
+---
+
+Version `0.52.0` of Spectre.Console has been released!
+
+Exciting things are happening. We’ve merged support for my love child, OpenCli, in this release. That means you can now pass the parameter `--help-dump-opencli` to your application to get an [OpenCli](https://opencli.org) description dumped to stdout.
+
+## What's Changed
+
+* Add OpenCLI integration to Spectre.Console.Cli by [@patriksvensson](https://github.com/patriksvensson) in [#1909](https://github.com/spectreconsole/spectre.console/pull/1909)
+* Fix OPENCLI_VISIBILITY_INTERNAL to DefineConstants concat by [@devlead](https://github.com/devlead) in [#1912](https://github.com/spectreconsole/spectre.console/pull/1912)
+
+**Full Changelog**: https://github.com/spectreconsole/spectre.console/compare/0.51.1...0.52.0
