Fixed dark mode checkbox

[Computroniks]

The border colour of the checkbox has been changed to make it more
visible to the user when the dark mode is in use.

Description

Previously, the check button with the label Remember me on the login page was near invisible for users using the dark mode due to the default bootstrap border colour being used. This PR fixes that issue by changing the border colour to $dark-border-color.
