Fix Stylelint configuration

[MellyGray]

Stylelint is not functioning as expected. It should enforce rules such as 'declaration-colon-space-after' to correct instances like padding:15px; to padding: 15px;, but it appears to be malfunctioning.

To reproduce the issue, edit an SCSS file by removing the space after the colon, then execute npm run lint:stylelint. You'll notice that the rule is not being applied, even though it is typically included in standard Stylelint configurations.
