Are you defining an alias or using a default alias?

[joyously]

It looks like a typo, but not sure if it was once called something else (like an alias)...
In site/notes/2024/jj tip ignore gh-pages by default.md
there is one reference to builtin_immutable_heads() and 5 references to buildin_immutable_heads(). The text talks about using the default one, but in that case it is misspelled.

Just a typo – thank you! I’ll fix it in a bit!
