Fixing reference in Typography sample (#207)

* Fixed references in Typography sample.

body1/body2/h4 don't exist in M3 Typography. The options are {display|headline|title|body|label}{Small|Medium|Large}.

* Update TextDownloadableFontsSnippets.kt

Typography should use m3 import.

* Apply Spotless
