Telemetry(amazonq): Discrepancy between NumOfUnitTestCasesGenerated with LinesGenerated and CharsGenerated

[Randall-Jiang]

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

Description

The lineOfCodeGenerated and charOfCodeGenerated mismatch numOfUnitTestCaseGenerated which returned from backend. There are 3 situations:

1. Job failed: The IDE would send a non zero numOfUnitTestCaseGenerated telemetry while the lineOfCodeGenerated and charOfCodeGenerated are 0s.
2. Job success, test file not exist: If there is no corresponding test file in the package before generate unit test, both lineOfCodeGenerated and charOfCodeGenerated will be 0.
3. Job success, test file already exist: If there is a corresponding test file already exist, the values for lineOfCodeGenerated and charOfCodeGenerated are still incorrect. Instead of reflecting the newly generated code, the IDE returns the existing test file's total line and character counts.

I implement a new function called getGeneratedFileContent and correct the calculate logic
