Potential Commit/PR that introduced the regression

PR #13336

NestJS version

11.0.1

Describe the regression

Before v11 the default behavior of moduleIdGeneratorAlgorithm (which didn't really exist) was the hash one.
V11 introduced a reference algorithm and changed it to be the default. This is a regression and is not documented in the non-existing release notes of v11.
Even if we decide that the default value should be changed back, there is currently no way of controlling the value of moduleIdGeneratorAlgorithm in TestingModuleBuilder.
Please change the default value and allow to change the algorithm in TestingModuleBuilder.
