Deprecated Gradle APIs in use, will break in Gradle 8

[benjamin-bader]

They all appear to be from Dokka, as documented in this issue from 2021.

This issue is just a reminder to come back and look at this in advance of Gradle 8.

Well, turns out it's not Dokka, it's Kotlin. Even as of 1.7.20, with Gradle 8.0 builds coming thick and fast, these still haven't been fixed:

~/D/thrifty ❯❯❯ ./gradlew -s clean check --warning-mode all                                                                                                                            ✘ 1
The TestReport.destinationDir property has been deprecated. This is scheduled to be removed in Gradle 8.0. Please use the destinationDirectory property instead. See https://docs.gradle.org/7.6/dsl/org.gradle.api.tasks.testing.TestReport.html#org.gradle.api.tasks.testing.TestReport:destinationDir for more details.

Not really sure what we can do other than eat popcorn and watch the show, waiting for JetBrains to fix their stuff.
