Fix python tool picking up wrong JAR version in Fat wheel mode

[parthosa]

Fixes #1355.

Currently, in fat wheel mode, the python tools uses a glob search to pick the the first JAR file that matches the pattern rapids-4-spark-tools_*.jar. This PR fixes this bug by selecting the exact JAR file that was packaged during the fat build.

Changes

• Extract the tools JAR file name that was packaged during the fat build and set it as a context variable fatWheelModeJarFileName
• Use the above the file name to get the correct tools JAR from the cache folder.

Testing

• Reproduced the case using steps provided in the issue description
  • Build fat wheel for 24.08.2 and then for 24.08.3-SNAPSHOT
  • 24.08.3-SNAPSHOT was picking up 24.08.2 JAR.
• Manually tested before and after the changes.

INFO rapids.tools.qualification: Using Spark RAPIDS Accelerator Tools jar version 24.08.3

Notes:

• We could have simplified this by getting the Tools JAR version from python and using it as a regex in fat wheel mode.
• However, being explicit with the packaged JAR avoids any confusion.
• This approach also allows for future enhancements, such as enabling build.sh to accept a custom JAR.
