[bug#33632] [PATCH] doc: Fix typo

[Laura Lazzati]

 a Funny fact about me is that when I studied English, for my last
Cambridge exam - sat for it being a teenager - I had to  be consistent
with the accent I had to choose. And I chose the British one. So even
nowadays my English is not that good, I tend to write centre, add the
u (behaviour)  add the r speaking : "the idea of", "pain in the neck'
... And I checked the word both in Cambridge dictionary and found it
as a noun, then in Oxford dictionary of collocations and the same.
Then I realized about it and only found it as a verb in American
English . Maybe that is why I thought it was a typo. Anyone whose
mother tongue is English can shed some light? Thanks for reverting :)
Regards!
