inconsistencies on L2Block-logs

[FilipHarald]

With #10210 and/or #10308 the API on L2Block for getting logs changed. - I'm sure it's for good reasons, but with the current implementation there are now inconsistencies between the txEffect.privateLogs and txEffect.unencryptedLogs.

The former is an array, and the latter is an object (with the logs/array in .functionLogs).

Also, @LeilaWang and @rahul-kothari it would have been great to have this update under "breaking changes" in the release notes here: #10282
(I do see them being mentioned further down the list)

Sorry for the confusion! We will also change the unencrypted logs to be an array. But since there are many changes happening on the public side, this has been given slightly lower priority. But this inconsistency is just temporary, and we will make sure to add it to breaking changes next time. Thanks for your feedback!
