Legacy 'bom FromFlatList' and 'bom FromCSV' still referenced at Readme_Workflow.md

Hi 👋

At https://github.com/sw360/capycli/blob/main/Readme_Workflow.md?plain=1#L45-L47 there are still reference to the arguments

• `CaPyCLI bom FromFlatList
• CaPyCLI bom FromCSV

AFAIK, they were removed formally at release 2.0 in favor of what I think would be:

• CaPyCLI bom convert -if text [-of {capycli,text,csv,legacy,legacy-cx,html,xml}]
• CaPyCLI bom convert -if csv [-of {capycli,text,csv,legacy,legacy-cx,html,xml}]

Thank you for reporting this, @rfuentess! I created a quick PR to fix this at #211.
