Fix submission info failure condition with gradle >= 7.6

[alexstaeding]

Gradle 7.6 introduced a change that affects the way the errors are presented for SubmissionWriteInfoTask. The names of the missing properties are no longer shown:

Old:

Could not evaluate onlyIf predicate for task ':mainWriteSubmissionInfo'.
> 
  There were some errors preparing your submission, please check your Gradle buildscript (e.g. build.gradle.kts).
  The following required properties were not set:
  studentId
  firstName
  lastName

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

Now:

Could not evaluate onlyIf predicate for task ':mainWriteSubmissionInfo'.
> Could not evaluate spec for 'Task satisfies onlyIf spec'.

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
