Update flag names

[RDPerera]

Purpose

The current usage of flags in the Ballerina EDI Tool (bal edi) deviates from the standard conventions followed by other Ballerina tools. To align the EDI tool with the rest of the Ballerina tool suite and improve consistency for users, This PR will update the following flag names:

1. Change -s flag to -i for input path:

   • -s, --schema is currently used to specify the input path for various commands. To adhere to the standard convention of using -i --input for input-related flags across Ballerina tools, I updated -s to -i.

2. Combine -O and -n flags into -p for output path and library name:

   • -O, --organization is used for specifying the output path in some commands, while -n, --name is used for providing the name of generated libraries in the libgen command. To streamline the usage and provide a more intuitive experience, both flags are combined into a single flag, -p, --package for specifying both the output path and library name.

Fixes ballerina-platform/ballerina-library#6045

But since this is a breaking change, lets update to next major version.
