[FEATURE] Support Multiple Boilerplate Options and Short Flag Mapping

[dhairyashiil]

Description:

The code has been updated to improve the CLI experience with the following changes:

• Processing Multiple Options: The code now processes each selected option in sequence, allowing multiple boilerplate templates to be generated in one run.
• Short Flag Mapping: Short flags (a, b, c) are mapped to full option names, making it easier for users to select options.

Impact:

• Users can generate multiple boilerplate templates quickly.
• Short flags make it easier to use the CLI with fewer keystrokes.
