What is the current behavior?

this a fix for the regression introduced by PR #11281

For example:

import { Logger } from '@nestjs/common'

class Foo {}

function foo() {
  return 'foobar'
}

const logger = new Logger()
logger.log(foo)
logger.log(Foo)
logger.log(class {})

You'll see:

/tmp/nestjs-app/node_modules/@nestjs/common/services/console-logger.service.js:150
            ? this.stringifyMessage(message(), logLevel)
                                    ^
TypeError: Class constructor Foo cannot be invoked without 'new'
    at ConsoleLogger.stringifyMessage (/tmp/nestjs-app/node_modules/@nestjs/common/services/console-logger.service.js:150:37)
    at ConsoleLogger.formatMessage (/tmp/nestjs-app/node_modules/@nestjs/common/services/console-logger.service.js:142:29)
    at /tmp/nestjs-app/node_modules/@nestjs/common/services/console-logger.service.js:131:43

What is the new behavior?

for the above code you will get this now:

Does this PR introduce a breaking change?

• Yes
• No ~ in the past (nest v9) we would see the whole class serialized. As this was broken since v10.0.0, I don't think that changing the format is a breaking change for v10 but I might be wrong. I can change the display format tho
