Update Serverless Workflow Temperature Conversion Example

[LuboTerifaj]

Description

There are several issues in Serverless Workflow Temperature Conversion Example.

Issues

• There is a wrong URL: CNCF Serverless Workflow specification in readme file.
• If you run the application conversion-workflow in local devmode you will get the following error:

• When running multiplication or subtraction service, there is an error:
  • ERROR [io.qua.run.Application] (main) Port 8080 seems to be in use by another process. Quarkus may already be running or the port is used by another application.
  • The ports in example should be configured properly, or there should be a guide how to configure the ports.
  • Although it is mentioned in "Testing the Application" section, the port must be specified before you run the service, not after.
• There is redundant '$' character is some commands in readme files

Acceptance criteria

The example can be run and it works as expected. The steps are properly documented in readme file.
