Subject: [PATCH] Fix don't quote prompt when `quote_char` is empty string

I already have a keymap to quote the prompt, so my current workflow is:
type query-> Quote prompt -> Start adding options

However I would like to create keymaps for some common options I use,
currently this not possible because when `quote_char` is emtpy, it still adds
backslashes before each character in prompt, and this breaks the search pattern

Usecase is for chaining mulitple `rg` options without, quoting
the prompt mulitple times, which is not the expected behavior when
`quote_char` is empty string.

E.g Consider this keymap

```lua
["<C-;>"] = require("telescope-live-grep-args.actions").quote_prompt {
        postfix = " --word-regexp ",
        quote_char = "",
    }
```

And I search for `tab`, then pressing `<C-;>`:

Before:

```
\"\t\a\b\"\ --word-regexp
```

After:

```
"tab" --word-regexp
```
