Remove spaces between segments

[JustinGrote]

Given this config:

- type: prompt
  alignment: left
  newline: true
  segments:
  - type: root
    properties:
      root_icon: ⚡
    style: plain
    foreground: '#E06C75'
  - type: exit
    properties:
      display_exit_code: false
      prefix: x
    style: plain
    foreground: '#C94A16'

  - type: text
    properties:
      prefix: ''
      text: ❯
    style: plain
    foreground: '#63F08C'

I want this:

To not have a space before the lightning bolt and after it. Is there a config setting I am missing?

FIgured it out looking at the source code, prefix and postfix if not set default to a space, you have to explicity set them to '' to get what I want.

Will PR a docs update to call this out.
