[feat] Use default terminal editor for writing SQL

[AbdelrahmanDwedar]

I use NeoVim almost for everything, I'd love to be able to write my SQL in lazysql with highlighting and LSP, which neovim offers for me

So in prefer of the Unix philosophy why don't we make it so you make a temporary file and use the default editor for writing SQL?

Would love to contribute with a PR but I'm kind of busy for now maybe if it wasn't implemented and I got some free time soon I'll implement it and make PR.
