fix(tailwind-integration): work-around missing tailwind base module

We currently don’t include the tailwind base module because it would
interfere with the bootstrap styles.

Unfortunately the tailwind base module also contains a lot of CSS
properties that are used in various utility classes to allow
fine-grained manipulation like `tw-translate-x-2` which would only set
the `tw-translate-x` CSS property and all the real work happening in the
`tw-transform` class which applies all these properties in a single
`transform` rule.

As we can’t include the tailwind base module because of said conflict,
we should at least define some of the missing CSS properties.
