Improve Bash logo

[alessandroasm]

Small improvement over the original logo:

• The pattern is now more consistent
• Colored the underline and changed the angle of it
• I'm using a darker shade of green (the one used on the chip is a little too bright for the logo).

Any suggestions are welcome :)

I was hoping for smth a little cleaner.

Here is my suggestion:

  ascii: |
    {0}             _._
    {0}         _.-'   '-._
    {0}     _.-'           '-._
    {0} _.-'                   '-._
    {0}|                        _,-|
    {0}|                    _,-'+++|
    {0}|                _,-'+++++++|
    {0}|             ,-'+++++++++++|
    {0}|             |++++ ++++++++|
    {0}|             |+++   +++++++|
    {0}|             |++  +++++++++|
    {0}|             |++++  +++{1}**{0}++|
    {0}|             |++   ++{1}**{0}++++|
    {0}'-,_          |+++ ++++++_,-'
    {0}    '-,_      |++++++_,-'
    {0}        '-,_  |++_,-'
    {0}            '-|-'
  colors:
    ansi:

That's a much cleaner design! I updated the PR with your suggestion.
