Add Tizen TFM to Sample

[JoonghyunCho]

Description of Change

This PR adds Tizen support on Maui Markup Sample!
Tizen Workload is not included in the default MAUI Workloads, so it will break unless you install the Tizen Workload.
Therefore, TF_BUILD condition is set for adding net7.0-tizen as the TargetFrameworks so it is only included in the CI environment where Tizen workload environment is prepared.

Strange - I don't see the Azure Pipelines running.

Did the YAML get scrogged in azure-pipelines.yaml? Like, a rogue spacing/indentation in the YAML?

[JoonghyunCho]

@brminnick sorry for that.. indentation in yaml..

Gosh darn YAML... 😆

The best tool I've found to avoid YAML parsing errors is this Visual Studio Code plugin. It's a YAML linter.

It's pretty good. It doesn't catch every possible YAML bug, but it detects a lot of them.
