• Yes, the URL of the associated JIRA ticket is https://issues.apache.org/jira/browse/SEDONA-229.

What changes were proposed in this PR?

This PR addresses the linter messages that were printing for the python adapter module. There were 3 of them:

• Missing newlines at end of files.
• Long line: an import line.
• Wildcard imports: The only ones in this module were for implicits/converters. I added an ignore regex to the scalastyle check so that these types of wildcard imports would be ignored (it seems that wildcard import is the correct way to import implicits).

How was this patch tested?

Standard build run. No structural changes were made to the code.

Did this PR include necessary documentation updates?

• No, this PR does not affect any public API so no need to change the docs.

@jiayuasu I'm not sure why the build is canceling. I would think it is unrelated to this PR, but if I'm missing something then please let me know.

@douglasdennis I think GitHub action ran into some internal issues. I wasn't able to restart the jobs. Let's wait for a few more hours. Hopefully GitHub can address this issue soon.

@douglasdennis OK. This is an intended warning from GitHub Action to remind us upgrade Ubuntu 18.04: actions/runner-images#6002

Will create a PR now to fix the GitHub Actions

@jiayuasu I tested the R build action with 22.04 and it worked fine, so you should be able to just replace 18.04 with 22.04 in that one
