Store raw installed versions for npm, pnpm, and yarn package managers instead of detected version

[kbukum1]

What are you trying to accomplish?

This PR updates the package manager version retrieval to store the raw installed version (including pre-release and build metadata, if any) for npm, pnpm, and yarn, instead of defaulting to a selected or guessed version. This change ensures that the exact installed version is captured, reflecting the actual environment more accurately.

Anything you want to highlight for special attention from reviewers?

• The installed_version method has been modified to retrieve and validate the raw version format directly from the package manager, falling back to the lockfile version if the format is unexpected.
• The memoization now caches the raw version, reducing calls to retrieve the version for the same package manager name.
• This approach improves accuracy by capturing the true installed version, which is essential for debugging and tracking specific package versions in complex environments.

How will you know you've accomplished your goal?

• Tests are included to verify that the raw version, including tags or metadata (e.g., 6.4.5-alpha), is stored and returned when available.
• Performance is maintained through memoization, ensuring minimal repeated calls for version retrieval.
• The functionality is confirmed to work as expected across npm, pnpm, and yarn, with correct fallbacks to lockfile versions if the installed version does not match expected patterns.
