docs: dt: writing-schema: mention coding style
Mention the usage of YAML coding style. Describe explicitly that four-space indentation in DTS examples is preferred, because: 1. The YAML's default two-space indentation for DTS code makes it significantly less readable. 2. Linux coding style tabs would introduce inconsistency (entire file is indented with spaces). 3. On the other hand, eight spaces would not align with example's opening ' - |' part. Four spaces makes the code nicely aligned with it.
