Fix curl command when we have prompt variable to resolve

[uudashr]

When we have prompt to resolve, error is raised.
The command is :Rest curl yank

### Anything
# @prompt lang The accepted language 
GET https://httpbin.io/anything/hello
Accept-Language: {{lang}}

This fix the issue by wrapping it inside nio run function

Thank you for the contribution! The patch seems good but unfortunately I cannot reproduce the issue on Neovim v0.11.3 (which is quite strange tbh). Can you share the version you are using?

[uudashr]

❯ nvim --version
NVIM v0.11.5
Build type: Release
LuaJIT 2.1.1765228720
Run "nvim -V1 -v" for more info

Merging it. Thank you for your contribution again!

It might be related to nvim-neotest/nvim-nio@230439d. A Jan 16, 2024 commit

They introduce the opts has strict? field that is defaulted to true.

But I still do not understand how it can happen, like maybe regular updates might causing this.
