Update Bundler deprecation unsupported check to use detected version

[kbukum1]

What are you trying to accomplish?

This PR updates the handling of deprecation and unsupported checks for Bundler by ensuring that detected_version is consistently used instead of raw_version.

This change improves the accuracy of deprecation notices and resolves edge cases where raw_version is either nil or different from the detected_version. It also refines the notice generation and logging behavior to handle all scenarios correctly.

Why?

• To ensure the consistency and correctness of version checks across Dependabot's ecosystem.
• To fix potential issues with mismatched version usage in deprecation and unsupported logic.
• To enhance the reliability and clarity of notices for deprecated and unsupported versions.

---

Anything you want to highlight for special attention from reviewers?

• The logic in unsupported? and related methods was updated to handle cases where raw_version is nil.
• Comprehensive test cases have been added to cover scenarios where:
  • detected_version is deprecated or unsupported.
  • raw_version is nil, deprecated, or different from detected_version.
• The NoticeHelpers module was updated and thoroughly tested to ensure proper notice generation and logging behavior.

---

How will you know you've accomplished your goal?

• All tests, including the complete test suite for NoticeHelpers and deprecation logic, pass successfully.
• Deprecation and unsupported checks now use detected_version consistently, addressing any discrepancies.
• Notice generation and logging correctly reflect the updated logic, including edge cases.

The code changes look relatively straightforward, but I had some questions about the tests...

Had a good call with @kbukum1 and this seems relatively straightforward to me. And if I'm missing something and it goes sideways, it shouldn't break things too badly.
