feat: Allow providing zipfile by name

[finger563]

Description

• Change zipfile-id to not be required and have default value of ''
• Add input zipfile-name (also not required) with default value of ''
• Add steps to check that exactly one of zipfile-id and zipfile-name is set

Motivation and Context

In some cases (such as via matrix strategy) you cannot easily use the zipfile-id as input because getting the output from matrix steps can be tricky. Allowing name to be provided helps in such cases.

How has this been tested?

It hasn't yet. 😅

• Added validation steps to enforce that exactly one input is provided
• Updated README documentation to describe the new usage option

File	Description
action.yml	Modified inputs and added validation steps for mutually exclusive zipfile inputs; updated download-artifact step
README.md	Updated documentation and examples to highlight the new input option

[Copilot]

In the download-artifact step, both 'zipfile-name' and 'zipfile-id' are always passed to the action. Consider conditionally providing only the set input, so that the action receives a single valid value and avoids potential unexpected behavior when one of the inputs is empty.
