Bind to both emacs and vi-insert keymaps in Bash

[akinomyoga]

Thank you for reviewing all the PRs that I submitted so far!

This is the final PR. Unlike the previous ones, this is a suggestion for a change.

Problem: Bash has several keymaps depending on the current editing mode (i.e., the emacs editing mode or the vi editing mode). The default keymap for the vi editing mode is separate from the one for the emacs editing mode. Currently (in the master branch), the Bash keybindings are only set up in the current keymap. If the user changes the editing mode after eval "$(mcfly init bash)", the keybindings become unavailable because the default keymap is switched.

For example, with the following bashrc, the keybindings are inactive:

# bashrc
eval "$(mcfly init bash)"
set -o vi

Solution: This PR registers the keybindings to both keymaps by explicitly specifying a keymap to register the keybindings.
