plugins: improve config, remove unused plugins

- Updates the configuration according to the indent blankline plugin
  version 3.
- Removes the ZenMode plugin as I should have done long ago.
- Lazy loads the Rainbow CSV plugin.
- Adds a keymap (<leader>ch) for the command history picker of
  telescope.
- Removes the kickstart big comment on top of the init.lua file.
- Removes the config file that I don't remember the utility.

-Kickstart.nvim is *not* a distribution.
-
-Kickstart.nvim is a template for your own configuration.
-  The goal is that you can read every line of code, top-to-bottom, understand
-  what your configuration is doing, and modify it to suit your needs.
-
-  Once you've done that, you should start exploring, configuring and tinkering to
-  explore Neovim!
-
-  If you don't know anything about Lua, I recommend taking some time to read through
-  a guide. One possible example:
-  - https://learnxinyminutes.com/docs/lua/
-
-  And then you can explore or search through `:help lua-guide`
-
-
-Kickstart Guide:
-
-I have left several `:help X` comments throughout the init.lua
-You should run that command and read that help section for more information.
-
-In addition, I have some `NOTE:` items throughout the file.
-These are for you, the reader to help understand what is happening. Feel free to delete
-them once you know what you're doing, but they should serve as a guide for when you
-are first encountering a few different constructs in your nvim config.
-
-I hope you enjoy your Neovim journey,
-- TJ
-
-P.S. You can delete this when you're done too. It's your config now :)
