Docs: Document that `has_block()` does not check reusable blocks. 

Since the function only checks the raw, non-parsed post content, reusable blocks are just a `core/block` type and nothing more at that point.

In order to also check reusable blocks, the content needs to be parsed using `parse_blocks()` first.

Props vyskoczilova, peterwilsoncc.
