fix(confirmDialog): force background colour on delete button ('Clear project' dialog)

[alxpez]

Description

Force background colour of the delete button (from 'Clear project' dialog), to keep the provided CSS rule over all others. Added !important rule to the existing button class.

Motivation and Context

As explained in #22, the lack of accent colour in this button, involves a lost of context over the action triggered.

How Has This Been Tested?

Used chrome devtools to confirm that the styles weren't overwritten by any other underlying CSS rule.
