This behavior can be controlled with the `gotestjsonbuildtext` setting.
Using `gotestjsonbuildtext=1` restores the 1.23 behavior.
This setting will be removed in a future release, Go 1.28 at the earliest.

Go 1.24 changed [`crypto/rsa`](/pkg/crypto/rsa) to require RSA keys to be at
least 1024 bits. This behavior can be controlled with the `rsa1024min` setting.
Using `rsa1024min=0` restores the Go 1.23 behavior.
