Add Metrics Collection for Composer Ecosystem: Package Manager and Language Details

[kbukum1]

What are you trying to accomplish?

This PR enhances metrics collection for the Composer ecosystem by adding the following details:

• Package Manager Raw Version: Captures the raw version string for better tracking and debugging.
• Language Raw Version: Logs the raw version of the language used for Composer projects.

Why:
These additions improve observability and provide detailed insights for Composer ecosystem metrics, helping to better understand versioning and compatibility issues.

is it possible to return N/A in case this is also not defined instead of nil?

This is a instance object, It will be hard to return N/A in case if we don't have version. If we want to do that we need to return T.any(String, Ecosystem::VersionManager), 2 different types which will make it more complicated.
