Tiny tweak to `couple`'s docs to help vim's LSP

I've loving Uiua, and it's continually impressive with how fast its evolving, and I'm almost embarrassed to ask for this miniscule change, and I can absolutely live without the tweak being made but...

The following (I think) defines the docs for the language,

uiua/src/primitive/defs.rs

Line 746 in db4aab7

/// By default, arrays with different shapes cannot be [couple]ed.

and looks great in the docs

and in VsCode:

But in my editor (coc.nvim via neovim), it looks like a typo:

Could we change the line to be

/// By default, arrays with different shapes cannot be [couple]'ed.

to make it more clear in text-only editors?

Thank you!
