> But, you might wonder how does a Tree-sitter grammar look like,
How does $thing look?
or
What does $thing look like?
Similarly, one often hears "Where are we at?" It is common enough to be seen as a regionalism.

I wonder if it's one of those little things that's surprisingly rare, like the th sound.
I’m a native English speaker who says “Where are we at”. I think it’s informal, but I never considered it to be wrong or awkward like the first example. Perhaps I’m in the region where it’s common.
Often elided to "Where we at?".
It's dialect, I wouldn't use either in formal/technical writing, but I would unselfconsciously say the latter, as in "ok, moving down the agenda, where we at with item 3?".

In either case, I agree the right word is "what" not "how". The comma after "but" bugs me tremendously. The colon can be replaced by an em dash (—) if the writer prefers it—but I would not use a question mark for the second clause without separating it from the first "but you might wonder" in some way.
The comma left in alternative #1 is to needed (recommended?) because the "and" is joining two clauses with different subjects. I think it's not strictly needed in alternative #2 because it's really "(but you might wonder (what a tree sitter looks like and how to create one for a language))" where the inner term is a list of things the reader might wonder, and lists with only two items do not take a comma before "and"
I would also prefer "Where are we?" over "Where are we at?"
Not an English speaker, so just my $0.02.
One issue that I remember was the web application to test the grammar needed an exact version of the emscripten stuff. And I had to sort out what that version was myself.
