create_test failing on pub failures #89759
Description
I am mainly seeing this in Engine rolls, which are very backed up, for example here:
First:
16:55 +378 -1: test\commands.shard\permeable\create_test.dart: invokes pub offline when requested
ProcessException: Failed to find "../..\bin\cache\dart-sdk\bin\dart" in the search path.
Command: ../..\bin\cache\dart-sdk\bin\dart
#0 LocalProcessManager.start (package:process/src/interface/local_process_manager.dart:58:7)
#1 LoggingProcessManager.start (file:///C:/b/s/w/ir/x/w/flutter/packages/flutter_tools/test/commands.shard/permeable/create_test.dart:2814:18)
#2 _DefaultProcessUtils.start (package:flutter_tools/src/base/process.dart:425:28)

<asynchronous suspension>
#5 _DefaultPub.get (package:flutter_tools/src/dart/pub.dart:248:7)
<asynchronous suspension>
#6 CreateBase.generateApp (package:flutter_tools/src/commands/create_base.dart:451:7)
Then later:
Because flutter_project depends on flutter_lints any which doesn't exist (could not find package flutter_lints in cache), version solving failed.
