Show absolute paths in skipped file messages

[pranlawate]

When files are skipped, isort now displays their absolute paths in verbose mode, consistent with the "Fixing" messages. This improves debugging by making it clear which files are being skipped.

Changes:

• isort/main.py:1178 - Convert file_name to absolute path before appending
• isort/files.py:24 - Use full_path instead of just dirname
• isort/files.py:35 - Use absolute filepath instead of just filename

Fixes #2412

Do you have a particular reason for using os.path and Path?

[pranlawate]

Thanks for reviewing this PR.
I am still fairly new with Python devlopement so I honestly don't know which is better to use.

I tried to use what's present in the nearby lines of where I changed the code. In files.py line 34 uses os.path so I used the same on 35th and in main.py 1177 line uses Path so I used that on 1178.

I generally like using Path myself so I can make both lines use that or if you would prefer os.path, then I can use that as well.
I think I can raise another PR for using either os.path or Path throughout the code by studying which is more suitable for isort to have more uniformity. Will prove a good improvement for me as well as the code if you would like that.

[DanielNoord]

Could indeed be nice to do a followup to use Path everywhere.
If you do so, please make sure to do not do everything in a big PR. Those are more likely to stall due to maintainers never having enough time to review big PRs.

Small PRs like this can be easily reviewed with little effort and merged to main soon :)
