Use tabbed code blocks to make the spec easier to read #580
Description
Currently, the spec shows examples in multiple serializations, where typically people are only interested in a single format depending on their use case, in my case this is JSON.
Lots of docs out there which have multiple snippet variants use tabs. Ideally, all tabs are linked, so switching one snippet to JSON switches all of them. I think SPDX would benefit from the same.
For mkdocs, there are extensions for this purpose, an example is shown here: https://squidfunk.github.io/mkdocs-material/reference/content-tabs/#configuration.
