Input type file uses white outline on focus in general settings page

[Ifycode]

Based on the fix I made here in PR 259 that should affect all buttons on the site, button elements that should have been skipped now receive focus - this is the reason why the buttons are not skipped in the screenshot below.

Describe the bug:

Input type file has a white outline when in focus instead of the one applied to other input types.

Screenshot:

Where was the bug observed:

http://localhost:3000/settings/general

Steps to reproduce the behavior:

1. Login to your account.
2. Go to setting > general.
3. Navigate to the input type file with the tab key.

Suggestions:

• I suggest the same styles applied to the other inputs/textarea should be applied to input type file too (that is if there's no other plan for input type file).
• Also, what if the generated API key is also made to receive focus?
