Fix image from Accounts

[jairockman]

Hi, this is more a improvement on the visualization of the plugin, in the accounts section:

You can edit these lines:

Line 85

 $image                                   ="<img src='" . $CFG_GLPI["root_doc"] . "/plugins/accounts/pics/cadenas.png' title='" .
                                                          _n('Encryption key', 'Encryption keys', 2, 'accounts') . "' alt='" .
                                                          _n('Encryption key', 'Encryption keys', 2, 'accounts') . "'>";

With:

$image = "<i class='fas fa-lock fa-2x' title='" . _n('Encryption key', 'Encryption keys', 2, 'accounts') . "'></i>";

And get something like more Accounts:

Instead of this:

Get this:

• Version of the plugin :
  2.4.1

• Version of your GLPI :
  9.53
