* Partially revert "Update dependabot config (#29536)"

This partially reverts commit b483f80b.

* dependabot: switch to `increase_versions`

Use our example shortcode's `class` parameter instead.

* Remove mention of icons from migration since they're not part of the core project

* Cleanup icons page to mention Bootstrap Icons

* Add variables for shades and tints of each major color

* getting-started/theming.md: use a `range`.

Now it should properly ignore the current published karma-browserstack-launcher versions

Fixes dart sass compatibility.

Add optional `$color` argument to `button-variant()` and
`button-outline-variant()` for additional flexibility.

By the time v5 stable will be out, 8 will be EOL (December 2019).

This way we match the Travis CI behavior, and it's inherited by all steps.
