docs: typo in a table field name

[Bilal2453]

the field name is no_truncate not no_trunate, it is correctly defined in the code.

I think the true|false format is also inconsistent, it will make things harder when generating the docs, should simply be something like { no_truncate: boolean }, or the more consistent

`flags`:
   `no_truncate`: `boolean`

update:
There is also a new **Note** format that was introduced with 8e2f306.
But maybe I will tackle those later when I progress with https://github.com/Bilal2453/luv-docgen.
