fix(chezmoi): add hidden=false to fzf picker (#6095)

## Description
Since #5275, the fzf picker has changed to use the `files` picker
instead of `fzf_exec` like before.

That means it also inherits the options of `files` picker, where `hidden
= true`. Just the command had been changed to use the `chezmoi` command,
but it doesn't make sense to have `hidden = true`, since it just appends
`--hidden` to the command which was supposed to be `fzf`, but now with
`chezmoi` it's not recognized.

Add `hidden = false` to the `files` picker when the command is chezmoi.
