Docs feature request: BNF or EBNF for Tolk language

[al8n]

Is your feature request related to a problem? Please describe.

Hi, I think the current language guide is not enough for a deep understanding of the tolk language, it is better to provide the grammar details like solidity docs: https://docs.soliditylang.org/en/latest/grammar.html

Describe the solution you'd like

Providing a detailed tolk language grammar like what solidity do in https://docs.soliditylang.org/en/latest/grammar.html#
