style(init): Cleanup the unknown shell message (#2444)

Browse Source 
* style(init): Cleanup the unknown shell message

Have make a small change to the message that is printed when an unknow
shell is used. This correct the placement of the trailing `"` so that
the two training new lines are correctly printed and updates the list of
supported shells.

* refactor(init): consolidate unknown shell errors

Have consolidated the two unknown shell errors

* refactor(init): Quote the shell name in the output

Quote the shell name in the script and combined the shell_name and
shell_basename to simplify the code a little.
