Remove push event settings from dotnet-macos.yml

This commit modifies the `dotnet-macos.yml` configuration file by removing the `push` event settings for branches and paths. The specific lines that restricted the `push` event to the `main` branch and ignored changes to Markdown files have been deleted, which may impact the build process for repository pushes.
