Fix: Do not suggest implicit activation message when engine does not support it

[Ishiezz]

Fixes #251898

Summary

This PR addresses the issue where the linter would incorrectly suggest bumping the engine version to ^1.75.0 even when the extension author intentionally targeted an older version. It also fixes a bug in the version check logic that would have caused failures for future major versions (e.g., 2.0.0).

Changes

• Updated Version Check: The logic major >= 1 && minor >= 75 was flawed because it would fail for version 2.0.0 (since 0 < 75). I updated it to correctly handle major > 1.
• Removed Warning: Removed the diagnostic that suggested bumping the engine version when implicit activation is not supported, as requested in the issue.
• Cleanup: Removed the unused bumpEngineForImplicitActivationEvents variable.

Verification

• Verified the version check logic with a standalone script:
  • 1.74.0 -> Correctly identified as NOT supporting implicit activation.
  • 1.75.0, 1.80.0 -> Correctly identified as supporting it.
  • 2.0.0 -> Fix verified: Now correctly identified as supporting it.
• Compiled the extension-editing extension successfully with gulp compile-extension:extension-editing.
