Fix typo in supergirl_(my_adventures_with_supermam)

BUR #61867 is pending approval.

rename supergirl_(my_adventures_with_supermam) -> supergirl_(my_adventures_with_superman)

Just fixing the typo "supermam" to "superman"

Why do we have a tag that's just my_adventures_with_superman supergirl?

Now that you mention it, I'm not sure...

Perhaps just made to disambiguate this version of the character from some of the other specific supergirl tags? For example, there's also supergirl_(dcau) (though it doesn't return the same results as dc_animated_universe supergirl). I don't know enough about any of the specific shows or the general character to really say anything concrete.

Cutting down on tagmaxxing.

Is there a standard about when a tag is used for a new variance and when it isn't?

I can kinda see how Absolute Batman looks distinct enough, but Absolute Superman generally just looks like normal Supes with medium hair and Lego Batman doesn't have his own tag

The superhero tags currently have their own messes to deal with regarding civilian versus superhero tagging, but the main rule of thumb is if a chartag can easily be substituted with a chartag + copytag search query, a more specific chartag isn't necessary.

I guess that explains why Teen Titans (2003)'s designs don't have its own tags, but that sounds like a decent amount of cutting down too.

There's a trend of crossing over different incarnations of Supergirl, I think the tags are useful.
