Subject: [PATCH] feat(picker): add toggle_regex for grep (#1594)

## For people who want to use it NOW!

Use `init` to hack the latest version before this PR merge.
```lua
{
  "folke/snacks.nvim",
  init = function()
    local sources = require("snacks.picker.config.sources")
    sources.grep.toggles = {
      regex = { value = true },
    }
    sources.grep.win = {
      input = {
        keys = {
          ["<a-r>"] = { "toggle_regex", mode = { "n", "i" }, desc = "Toggle Regex" },
        },
      },
    }
  end,
},
```


## Description

This PR adds a new keymap `<a-r>` for toggling the regex in grep picker.

It allows user to get faster when searching some special strings like
`$props()`, or just put a part of line `test to jump faster.
