[Followup] Fix Drupal.Commenting.FunctionComment.MissingReturnType returns for NULL

Can the MR be updated for 11.x please.

11.x is the current development branch, so code has to be committed there first to be backported.

So searching for " but return statement is missing" there still appear to be 89 instances in phpstan-baseline. Were those left out specifically?

Give them a closer look.

For example this one: \Drupal\Core\Database\Query\Delete::execute

Think it needs to be documented why we are skipping these 89 instances

Some functions are

save(),
getFormId(),
validateForm(),
etc

If the inherited docs say it returns a value and we are leaving in the phpstan file think it needs to be stated why.
