SCSS optimizations for text

# (not really a) Bug Report (but a minor optimization)

## Prerequisites

* [x] Can you reproduce the problem on TYPO3 v13.4 LTS
* [x] Did you perform a cursory search to see if your bug or enhancement is already reported?

## Description

1) The files compat/_text.scss and components/_text.scss both contain same ".awesome" SCSS code.
2) It's not needed to add ".h1.awesome" - SCSS generates this ".h1" class from "h1.awesome". Same for h2 etc.

### Expected behavior

Clean and lightweight code ;)
