We decided to remove the grammar blocks from the spec in WDL 1.1.1, for two reasons:

They are likely incorrect/incomplete
They use a non-standard notation

Instead, we should have the BNF grammar, either as an appendix to the spec, or alongside the ANTLR grammar in the repo.

We can use this as a starting point: https://github.com/broadinstitute/winstanley/blob/44896516cef2dadac35e7af0fc0d5c4dc8de2ff2/src/winstanley/wdl.bnf#L4

This issue should move to the wdl-parsers repo if we decide to have the BNF grammar as separate from the spec.
