Minor typo

[eKristensen]

Hi

You got a typo here:

gentle-intro/src/nom-intro.md

Line 131 in 11650e1

- `Imcomplete` - more data needed

And here:

gentle-intro/src/nom-intro.md

Line 216 in 11650e1

`Imcomplete` error. Nom knows that "bye" may be followed by a name and wants us to give it more

Imcomplete should be Incomplete
