TST: repr of Arrow-backed object (GH #48238)

[a-reich]

• closes BUG: series created from pyarrow array with date32 type in 1.5rc0 can be created but not displayed #48238
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• [N/A] Added type annotations to new arguments/methods/functions.
• [N/A] Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

The actual issue in #48238 was fixed already, only test is needed - I basically just stole the test from #48238 (comment).

Also, this is my first time contributing here so sorry if I get the process wrong. Thanks!

Not sure what to do about the failing CI jobs since they don't seem to be coming from the file I touched :-(

Ah so I ran into this same issue in #48258. I think there's some cached state in the testing causing unrelated tests to fail.

Would be very welcome for you to dig into why this is happening, but I would say this isn't a good first issue necessarily. Let me know if you'd like to continue otherwise I recommend tackling a separate issue.

Okay, I don’t think I’m the best person to tackle the broken CI issue unfortunately, as I’m not super knowledgeable about advanced aspects of GHA or whatever else could be causing cache problems.

Thanks for letting me know @a-reich. I'll close this pull request for now then to maybe let another user tackle this if interested. Can reopen if you are interested in tackling this issue again
