Typo and formatting issues

''Exposes port [80]{custom-style=Code} and [443]{custom-style=Code}.'' The ''custom-style=code'' should be parsed, affect the string which preceeds it and not be visible in the PDF document. And one more thing, the content of the Dockerfile specifies port 44 when it should be 443.

The content from https://learn.microsoft.com/en-us/dotnet/architecture/dapr-for-net-developers/getting-started doesn't have these issues
