Revert "Make text option an argument instead of an option"

This reverts commit c767a0a.

This changes --text from typer.Argument to typer.Option

This is a breaking change. It puts text on the same level as the other options like image or barcode.
It is breaking because it now requires any text to be preceeded by `--text`.
